Here is this week's space weather and geophysical report, issued 2024 Aug 26 0150 UTC.

Highlights of Solar and Geomagnetic Activity 19 - 25 August 2024

Solar activity was at R1 (Minor) to R2 (Moderate) levels on 19-24 Aug. A total of 18 R1 (Minor) flares were observed on 19-24 Aug from Regions 3785 (S15, L=107, class/area Dai/100 on 18 Aug), 3796 (S03, L=353, class/area Dki/380 on 23 Aug), 3800 (S27, L=331, class/area Eai/160 on 25 Aug) and 3801 (N07, L=300, class/area Cso/140 on 23 Aug). A total of two R2 (Moderate) flares were observed from Regions 3796 and 3800. No Earth-directed CMEs were observed from any of these flares. Region 3794 (S17, L=040, class/area Dai/240 on 20 Aug) produced a C5.9 flare at 23/0210 UTC. LASCO C2 imagery observed a CME off the W limb with a likely Earth-directed component. The periphery of the slow-moving ejecta is forecasted to brush by Earth late on 27 Aug to early on 28 Aug.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at low to moderate levels.

Geomagnetic field activity was at mostly quiet to isolated unsettled levels. The solar wind field on 19-25 Aug was at mostly nominal levels for the period. Bz reached a maximum high of 11 nT early on 23 Aug while the Bz component reached -10 nT during that same time. Wind speeds ranged from a high of 435 km/s to a low of 300 km/s. The phi orientation was mostly positive through the period.

Forecast of Solar and Geomagnetic Activity 26 August - 21 September 2024

Solar activity is likely to be at moderate levels throughout the outlook period due to mulitple complex regions on the visible disk and regions anticipated to return.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels during the outlook period.

Geomagnetic field activity is expected to be mostly quiet. Unsettled to active conditions are possible on 27-28 Aug due to potential CME effects from the 23 Aug CME. Unsettled conditions are possible on 17-18 Sep due to positive polarity coronal hole influence. Mostly quiet conditions are forecast for 26 Aug, 29-31 Aug, 01-16 Sep and 19-21 Sep. The long-term forecast only contains recurrent solar wind features like CH HSSs and SSBCs. CMEs will be added as they occur.

Here is this week's space weather and geophysical report, issued 2024 Aug 19 0225 UTC.

Highlights of Solar and Geomagnetic Activity 12 - 18 August 2024

Solar activity was at high levels on 14 Aug and moderate (R1-Minor) for the remaining days between 12-18 Aug. Region 3784 (N14, L=115, class/area=Dkc/700 on 14 Aug) produced the strongest event of the period, an X1.1/2b (R3-Strong) flare at 14/0640 UTC. Associated with the flare were Type II (est. 516 km/s) and Type IV radio sweeps, as well as a subsequent CME signature observed in LASCO imagery. Analysis and modeling of the CME suggested an Earth-directed component from 17-18 Aug. The remaining days in the summary period, outside of 14 Aug, observed 16 other R1 (Minor) events. The regions associated with R1 events were 3777 (S09, L=209, class/area=Ekc/460 on 09 Aug), 3780 (S12, L=170, class/area=Fkc/1250 on 08 Aug), 3784, 3785 (S15, L=107, class/area=Dai/100 on 18 Aug), and 3790 (S12, L=024, class/area=Dkc/280 on 18 Aug).

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at low to moderate levels.

Geomagnetic field activity reached G4 (Severe) levels on 12 Aug due to influence of a CME that left the Sun on 08 Aug. An X1.3/2b flare at 08/1935 UTC from Region 3777 produced a Type II (est. 1,026 km/s) and Type IV radio sweep as the CME lifted off of the Sun. Its arrival increased total magnetic field strength to a peak of 21 nT, and Bz reached as far south as -20 nT. Solar wind speeds peak just over 500 km/s. The geomagnetic field responded with a series of G3 (Strong) synoptic periods and an isolated G4 (Severe) during the 12/1200-1500 UTC synoptic period. As the CME waned, G1 (Minor) conditions on 13 Aug decreased to active levels on 14 Aug. Quiet to unsettled conditions characterized 15-16 Aug. The onset of a CME associated with the X-flare (R3-Strong) from Region 3784 arrived with a shock at L1 around 17/1330 UTC. Total magnetic field strength increased from 7 to 25 nT and Bz briefly reached -21 nT shortly after. Solar wind speeds increased from the low 300's to around 475 km/s. The geomagnetic field responded with an isolated G3 (Strong) geomagnetic storm during the 17/1200-1500 UTC synoptic period. Bz turned northward and remained there through the end 18 Aug. This resulted in a drop in subsequent geomagnetic activity to below G1 (Minor) levels on 18 Aug.

Forecast of Solar and Geomagnetic Activity 19 August - 14 September 2024

Solar activity is likely to be at moderate levels throughout the outlook period due to multiple complex regions on the visible disk and ones anticipated to return from the Sun's farside. A slight chance for R3 (Strong) activity is forecast over the next week due to the currently analyzed monitored active regions on the Sun's nearside.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels during the outlook period.

Geomagnetic field activity is expected to be mostly quiet. Unsettled conditions are possible on 22-23 Aug due to coronal hole influence. The long-term forecast only contains recurrent solar wind features like CH HSSs and SSBCs. CMEs will be added as they occur.

Here is this week's space weather and geophysical report, issued 2024 Aug 12 0219 UTC.

Highlights of Solar and Geomagnetic Activity 05 - 11 August 2024

Solar activity was ranged from moderate to high levels. 34 events, which ranged from R1-R3 (Minor-Strong), were observed during the week. Region 3767 (S10, L=318, class/area=Dso/beta on 27 Jul) produced the strongest flare of the period, an X1.7/Sf at 05/1340 UTC. Two other regions produced X-class activity with an X1.1/2b at 05/1527 UTC from Region 3780 (S12, L=173, class/area=Fkc/1280 on 09 Aug) and an X1.3/2b flare at 08/1935 UTC from Region 3777 (S09, L=209, class/area=Ekc/460 on 09 Aug).

CME activity observed over 07-08 Aug from multiple sources were analyzed and considered likely to be Earth-directed with a transit time of 3-4 days. An additional CME associated with an M5 (R2-Moderate) flare at 10/0237 UTC produced a faint halo signature first observed in SOHO/LASCO C2 imagery at 10/0312 UTC. Analysis and modeling suggested arrival on 12 Aug.

The greater than 10 MeV proton flux observed at geosynchronous orbit became slightly enhanced over 05-06 Aug, but well below the 10 pfu (S1-Minor) threshold due to energetic activity on the Sun's farside.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal background levels.

Geomagnetic field activity ranged from quiet to G1 (Minor) storm levels. G1 conditions were observed on 11 Aug, likely due to the influence of passing CMEs that left the Sun over 07-08 Aug. Total magnetic field strength increased to ~11 nT on 10 Aug and increased to a peak of 21 nT on 11 Aug. Solar wind speeds steadily climbed during that time from ~350 km/s to just over 500 km/s at the end of 11 Aug. The Bz component was primarily oriented neutral or northward which resulted in a limited geomagnetic response. A brief period of -20 nT was observed during the final hour of 11 Aug. The remainder of the summary period was at quiet to unsettled levels.

Forecast of Solar and Geomagnetic Activity 12 August - 07 September 2024

Solar activity is expected to reach moderate (R2-Moderate) conditions, with a chance for R3-Strong events, over 12-18 Aug due to multiple complex regions on the visible disk. R1 (Minor) conditions remain likely on most days through the end of the outlook period due to the anticipated return of multiple complex regions from the Sun's farside.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal background to moderate levels throughout the outlook period.

Geomagnetic field activity is expected to reach G2 (Moderate) levels on 12 Aug due to the passing of multiple CMEs from 08 Aug and 10 Aug. As CME influence wanes, active conditions over 14 Aug are likely to decrease to unsettled levels over 14-15 Aug. Unsettled conditions are again likely on 22-23 Aug in response to a recurrent CH HSS. The remainder of the outlook period is likely to be at quiet levels, excluding any CMEs that have yet to erupt with an Earth-directed component.

Here is this week's space weather and geophysical report, issued 2024 Aug 05 0210 UTC.

Highlights of Solar and Geomagnetic Activity 29 July - 04 August 2024

Solar activity was at high levels throughout the period. A total of 63 M-flares (51 R1-Minor events, 12 R2-Moderate events) and one X-flare (R3-Strong event) were observed during the course of the week from 13 unique regions. The largest event was an impulsive X1.5/2b flare at 29/0237 UTC, with associated 300 sfu Tenflare and 535 km/s Type-II sweep, from Region 3766.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels.

Geomagnetic field activity reached G1 (Minor) storm levels on 30 Jul-01 Aug due to the arrival and passage of multiple CMEs that left the Sun over 27-29 Jul. G1-G3 (Minor-Strong) storm periods were observed on 04 Aug following the arrival of a CME that left the Sun on 01 Aug. Quiet and quiet to unsettled levels were observed throughout the remainder of the period.

Forecast of Solar and Geomagnetic Activity 05 August - 31 August 2024

Solar activity is expected to be at moderate to high levels throughout the outlook period. M-class flares are expected with a chance for X-class flares through 31 Aug.

There is a slight chance for S1 (Minor) solar radiation storms throughout the outlook period.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels.

An Isolated period of G1 (Minor) storms are possible on 05 Aug due to waning CME influences. Geomagnetic field activity is expected to be mostly quiet and quiet to unsettled over 06-31 Aug.

Here is this week's space weather and geophysical report, issued 2024 Jul 29 0218 UTC.

Highlights of Solar and Geomagnetic Activity 22 - 28 July 2024

Solar activity reached moderate and high levels this period with a total of nineteen R1 (Minor) events and three R2 (Moderate) events observed throughout the week. The largest event of the period was an M9.9 flare at 28/0157 UTC from Region 3766 (S07, L=331, class/area=Dac/150 on 28 Jul). Shortly before this flare, the region produced an M7.8 flare at 28/0151 UTC. Associated with these two events were a 250 sfu Tenflare and a 1053 km/s Type II sweep. Region 3762 (S11, L=20, class/area=Fkc/440 on 28 Jul) was the most active region and produced an M7.7/1b flare at 28/1042 UTC, in addition to seven R1 events throughout the week.

Other notable activity included an Earth-directed CME, first visible in C2 imagery at 26/2124 UTC off the SSE, that was associated with a filament eruption late on 26 Jul. Another Earth-directed CME resulted from a long-duration M3.1 flare at 27/0546 UTC from Region 3662. The 27 Jul CME was faster than the 26 Jul CME and are likely to arrive concurrently beginning late on 29 Jul/early on 30 Jul. A full-halo CME associated with the M9.9 flare at 28/0157 UTC, and first visible in LASCO C2 imagery at 28/0224 UTC, is expected to arrive mid-to-late 30 Jul. A final Earth-directed CME followed an episode of dimming in the vicinity of Region 3768 (S16, L=4) at around 28/1400 UTC, and is expected to arrive as a glancing-blow late on 31 Jul/early 01 Aug.

A solar energetic particle event occurred early on 23 Jul as a result of far sided flare activity. The greater than 10 MeV proton flux reached S1 (Minor) storm levels beginning at 23/0300 UTC, reached a peak flux of 24 pfu at 23/1040 UTC, and decreased below S1 levels at 23/2350 UTC. The greater than 100 MeV proton flux reached the 1 pfu event threshold beginning at 23/0205 UTC, reached a peak flux of 1 pfu at 0430 UTC, and decreased below 1 pfu at 23/1510 UTC.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels throughout the period.

Geomagnetic field activity was at quiet to unsettled levels on 22-23 Jul, and at quiet levels on 24 Jul, under nominal solar wind conditions. Quiet and unsettled levels were observed on 25 Jul with the onset of CME influences late in the day. Periods of active conditions and G1 (Minor) storming were observed on 26 Jul in response to sustained CME influences and the onset of positive polarity CH HSS influences. Quiet to active levels prevailed on 27 Jul as CME and CH HSS influences diminished. Quiet and unsettled levels were observed on 28 Jul with the return of ambient solar wind conditions.

Forecast of Solar and Geomagnetic Activity 29 July - 24 August 2024

Solar activity is expected to reach moderate to high levels, with R1-R2 (Minor-Moderate) events likely to expected, and a slight chance for R3 (Strong) or greater events throughout the period.

No proton events are expected at geosynchronous orbit, barring significant flare activity.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to persist at normal to moderate levels throughout the outlook period.

Geomagnetic field activity is likely to reach G1 (Minor) storm levels on 29 Jul, G3 (Strong) storm levels on 30 Jul, and G2 (Moderate) storm levels on 31 Jul, all in response to the anticipated arrival and passage of multiple CMEs from 26-28 Jul. Quiet and quiet to unsettled geomagnetic field activity is expected to prevail throughout the remainder of the outlook period.

Here is this week's space weather and geophysical report, issued 2024 Jul 22 0507 UTC.

Highlights of Solar and Geomagnetic Activity 15 - 21 July 2024

Solar activity was at moderate to high levels. High levels were observed on 16 and 17 Jul due to an X1.9/1B flare at 16/1326 UTC from Region 3738 (S09, L=213, class/area Fkc/1140 on 14 Jul) and an M5.0/2b flare at 17/0639 UTC from Region 3743 (S08, L=162, class/area Dai/220 on 13 Jul). The X1 flare had accompanying Type II (398 km/s) and Type IV radio bursts, a Castelli U radio signature, as well as a CME of the W limb that was not Earth-directed. Region 3753 (N12, L=170, class/area Dai/100 on 16 Jul) and 3744 (N16, L=144, class/area Dso/180 on 12 Jul) produced a pair of M1 flares at 16/2124 UTC and 16/2206 UTC. Two associated partial halo CMEs were observed after 16/2312 UTC. Modelling of the pair indicated an arrival beginning at midday on 20 Jul followed by a secondary arrival early on 21 Jul. At 21/1610 UTC, a disappearing solar filament was observed in the vicinity of Region 3757 (N18, L=061, class/area Hax/060 on 17 Jul). An associated halo CME was observed at 21/1648 UTC. Initial analysis indicated an arrival on 24 Jul. Further analysis is in progress at the time of this writing.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels.

Geomagnetic field activity ranged from quiet to unsettled levels. Weak transient activity was evident on 15-16 Jul and possibly 19-20 Jul, however weak solar wind speeds in the 300-400 km/s range as well as a predominant northward Bz component led to only isolated unsettled periods on 15-16 Jul. Quiet conditions prevailed through 21 Jul.

Forecast of Solar and Geomagnetic Activity 22 July - 17 August 2024

Solar activity is expected to continue at moderate levels with M-class flares (R1-R2, Minor-Moderate) levels likely and a slight chance for X-class (R3, Strong) through 27 Jul as Regions 3751 (S08, L=092, class/area Ekc/410 on 19 Jul) and 3761 (S10, L=081, class/area Dki/300 on 21 Jul) rotate across the visible disk. Low to moderate levels are likely from 28 Jul through 17 Aug.

There is a slight chance for a greater than 10 MeV proton event exceeding the S1 (Minor) levels through 29 Jul due to the flare potential of Regions 3751 and 3761.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to continue at normal to moderate levels.

Geomagnetic field activity is expected to be at mostly quiet levels through 17 Aug barring any inbound CME activity. A potential for G1-G2 (Minor-Moderate) levels is likely for 24 Jul due to the arrival of the 21 Jul CME, however analysis is still in progress.

Here is this week's space weather and geophysical report, issued 2024 Jul 01 0220 UTC.

Highlights of Solar and Geomagnetic Activity 24 - 30 June 2024

Solar activity reached moderate levels on 24-25 Jun. The largest flare was an M1.8 flare from Region 3712 (S26 L=170, class/area=Eao/220) at 24/0417 UTC. Other M1 flares were observed from Regions 3713 (S14 L=153, class/area=Ekc/360), 3720 (S06 L=54, class/area=Dai/150), and 3723 (S19 L=08, class/area=Fai/210). Solar activity was at low levels for 26-30 Jun, with only C-class flares observed. Other notable activity included an approximately 35 degree filament erupted late on 24 Jun, centered near S19W58.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels.

Geomagnetic field activity was reached G4 (Severe) storm levels on 28 Jun due to the arrival of a CME that lifted off the Sun on 24 Jun. Total field strengeth reached 30 nT and the Bz component reached -22 nT. Solar wind speeds increased steadily from near 300 km/s to approximately 490 km/s. Active levels were reached early on 29 Jun due to continued CME influences. Quiet to unsettled levels were observed on 24-27 Jun, and 30 Jun.

Forecast of Solar and Geomagnetic Activity 01 July - 27 July 2024

Solar activity is expected to be low levels, with occasional M-class flares for the duration of the period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at moderate levels from 01-27 Jul.

Geomagnetic field activity is expected to be at unsettled to active levels on 01-03 Jul due to possible glancing influences from multiple CMEs. Unsettled to active levels are expected on 14-16 Jul due to influence from a recurrent, positive polarity coronal hole high speed stream (CH HSS). Quiet to unsettled levels are expected on 05-13 Jul and 17-27 Jul.

Here is this week's space weather and geophysical report, issued 2024 Jun 24 0141 UTC.

Highlights of Solar and Geomagnetic Activity 17 - 23 June 2024

Solar activity ranged from low to high levels. Region 3723 (S18, L=011, class/area=Dao/150 on 23 Jun) produced the strongest event of the period, an impulsive M9.3/1b flare (R2-Moderate) at 23/1301 UTC. Region 3719 (S15, L=067, class/area=Dao/230 on 23 Jun) also produced an R2 event with an impulsive M5.7/1b flare at 20/2316 UTC. 12 other low-level M-class (R1-Minor) events were observed from various regions throughout the week. No Earth-directed CMEs were identified with any of the flare events. Other activity included a Type-II radio sweep on 17 Jun and an additional Type-II radio sweep on 22 Jun. Both radio sweeps were associated with eruptive activity that was not on the Sun-Earth line.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels throughout the summary period.

No significant geomagnetic field activity was observed during the summary period. Quiet to unsettled levels throughout week. Solar wind conditions were influenced by the onset of a postive polarity CH HSS which increased wind speeds to peak near 600 km/s on 18 Jun. Wind speeds then steadily decreased to a low of 300 km/s late on 22 Jun. A weak transient feature was observed on 23 Jun with a southward Bz of -10 nT observed, but combined with the slow wind speeds, only unsettled levels were observed.

Forecast of Solar and Geomagnetic Activity 24 June - 20 July 2024

Solar activity is likely to reach moderate on 24-25 Jun due primarily to the flare potential from active regions near the west limb. A decrease to low levels, with a slight chance for M-class activity (R1-R2/Minor-Moderate), is likely from 25 Jun - 20 July.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at low to moderate levels throughout the outlook period.

Geomagnetic field activity is expected to reach unsettled levels on 24 Jun, 14-16 Jul, and 20 Jul due to anticipated influence from multiple, recurrent, CH HSSs. The remainder of the outlook period is likely to be at mostly quiet levels.

Here is this week's space weather and geophysical report, issued 2024 Jun 17 0202 UTC.

Highlights of Solar and Geomagnetic Activity 10 - 16 June 2024

Solar activity ranged from low to high levels. Region 3697 (S18, L=350, class/area=Fkc/410 on 03 Jun) produced the strongest flare of the period, an X1.5/Sf flare (R3 - Strong) at 10/1108 UTC. The region also produced two R2 (Moderate) and three R1 (Minor) events before it rotated around the W limb on 10 Jun. Region 3712 (S26, L=169, class/area=Ekc/1000 on 16 Jun) developed into the most complex region currently on the visible disk. Only R1 events have been produced by this region at the time of this report.

Other activity included filament channel eruption centered near S38E55 which began around 12/1100 UTC. Later that day, an M1.2/1n flare (R1) was observed from Region 3711 (S08, L=211, class/area=Dao/060 on 10 Jun) at 12/2246 UTC. Ejecta from these two events were analyzed. The results suggested potential for CME influence at Earth with onset over 14-15 Jun.

No proton events above the S1 (Minor) threshold were observed at geosynchronous orbit. However, an enhancement was observed which peaked just below S1 levels over 12-13 Jun due to activity on the Sun's farside late on 11 Jun.

The greater than 2 MeV electron flux at geosynchronous orbit was remained at background levels.

Geomagnetic field activity was elevated to active levels on 10-11 Jun, likely due to CME activity that occurred on the Sun over 08 Jun. Quiet conditions were observed from 12-14 Jun. Geomagnetic activity increased to G1 (Minor) geomagnetic storm levels on 15 Jun and active conditions on 16 Jun, likely due to multiple eruptive events on the Sun over 12 Jun.

Forecast of Solar and Geomagnetic Activity 17 June - 13 July 2024

Solar activity is likely to reach moderate levels over 17-24 Jun, primarily due to the flare potential of Region 3712 (S26, L=169, class/area=Ekc/1000 on 16 Jun). A chance for R1-R2 (Minor-Moderate) activity is likely to remain throughout the outlook period due to the anticipated return of multiple complex regions from the farside of the Sun.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to remain at normal to moderate levels.

Geomagnetic field activity is expected to range from quiet to active levels. Multiple, recurrent CH HSSs are likely to cause active conditions on 18 Jun and unsettled conditions over 17 Jun, 19-20 Jun, 22-23 Jun, and 30 Jun - 01 Jul. The remainder of the outlook period is likely to be mostly quiet.

Weather Charts by Shortwave Radio from Point Reyes, CA - WEFAX 22.527 MHz

Weather Charts by Shortwave Radio from Point Reyes, CA - WEFAX 22.527 MHz on 2024 JUNE 14

https://youtu.be/9N66y9HFX_Q

This video is a screen and sound capture of my reception of weather charts and images by shortwave radio, from a station in California running about 4 kilowatts of RF power.  This HF WEFAX (Weather Facsimile) service is on every day for ship (marine) weather dissemination so that ships out on the ocean can get weather charts and images not by satellite, but by receiving shortwave signals.

Here is a snippet from the published schedule from Point Reyes WEFAX Radio, callsign NMC, is as follows:

22527 kHz - tune offset 1.9 KHz

(thus I was tuned to 22526 KHz USB, based on this: "Unless otherwise stated, assigned frequencies are shown,  for carrier frequency subtract 1.9 kHz. Typically dedicated radiofax receivers use assigned frequencies, while receivers or transceivers, connected to external recorders or PC's, are operated in the upper sideband (USB) mode using carrier frequencies.")

Highlights of Solar and Geomagnetic Activity 03 - 09 June 2024

Solar activity ranged from moderate to high levels. Region 3697 (S18, L=350, class/area=Fkc/350 on 03 Jun) was the most active sunspot region this period and produced 14 (R1) Minor events and two R2 (Moderate) events; the largest of which was a long-duration M9.7/1f flare at 08/0149 UTC. Following the M9.7 flare, a SEP event commenced and a partial halo, Earth-directed CME was produced. Region 3697 also produced an M6.1/2b flare at 06/1506 UTC. Regions 3695 (N27, L=030, class/area=Cao/50 on 03 Jun), 3703 (S08, L=327, class/area=Dac/200 on 07 Jun), and 3709 (S10, L=218, class/area=Cai/140 on 09 Jun) each produced a single R1 event.

Solar radiation storm conditions were observed on 08-09 Jun, following the long-duration M9.7 flare at 08/0149 UTC from Region 3697. The greater than 100 MeV proton flux exceeded 1 pfu beginning at 08/0225 UTC, reached a peak flux of 8 pfu at 08/0625 UTC, and decreased below the 1 pfu threshold at 08/1455 UTC. The greater than 10 MeV proton flux exceeded the S1 (Minor) event threshold beginning at 08/0255 UTC, reached a peak flux of 1,030 pfu at 08/0800 UTC (S3/Strong), and decreased below S1 levels at 09/2125 UTC.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels throughout the period.

Geomagnetic field activity reached G1 (Minor) storm levels on 03 Jun due to positive polarity CH HSS influences. Quiet and unsettled levels were observed on 04-06 Jun. G2 (Moderate) storm levels were observed on 07 Jun, and active levels were observed on 08 Jun, due to CME activity. Quiet conditions prevailed on 09 Jun.

Forecast of Solar and Geomagnetic Activity 10 June - 06 July 2024

Solar activity is expected to reach moderate and high levels throughout the period. M-class flare activity is likely-to-expected with a varying chance for X-class flares.

No proton events are expected at geosynchronous orbit, barring significant flare activity.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels throughout the period.

Geomagnetic field activity is expected to reach G1-G2 (Minor-Moderate) storm levels on 10 Jun, and G1 levels on 11 Jun, due to the anticipated arrival of the 08 Jun CME. Quiet and quiet to unsettled levels are expected to prevail throughout the remainder of the outlook period.

Solar activity ranged from low to high levels throughout the period. Region 3697 (S18, L=350, class/area=Eki/420 on 30 May) was the most productive region this period and produced five X-class flares, and seven M-class flares; the largest of which was an X2.8 flare at 27/0708 UTC. Region 3691 (N25, L=042, class/area=Ekc/480 on 27 May) produced three M-class events and Region 3695 (N27, L=028, class/area=Cao/30 on 01 Jun) produced a single M-class flare. Other notable activity included a long-duration X1.4/2b flare at 29/1437 UTC from Region 3697, with accompanying Type II and IV radio emissions, and an Earth-directed partial halo CME that arrived on 31 May. Additionally, an impulsive X1.0/2b flare at 01/1836 UTC and a long-duration M7.3 flare at 01/1939 UTC, both from Region 3697, resulted in a CME that is likely to glance by Earth on 04 Jun.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels.

Geomagnetic field activity was at quiet and quiet to unsettled levels throughout much of the period. An isolated period of G1 (Minor) geomagnetic storming was observed early on 31 May due to CME activity.

Forecast of Solar and Geomagnetic Activity 03 June - 29 June 2024

Solar activity is likely to reach moderate and high levels throughout the period, with M-class flares likely and a varying chance for X-class flares through 29 Jun.

No proton events are expected at geosynchronous orbit

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels throughout the period.

Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic storm levels on 04 Jun, and active levels on 05 Jun, due to the anticipated glancing-blow arrival of the 01 Jun CME. Active contidiions are expected on 09 Jun due to CH HSS influences. Quiet and quiet to unsettled levels are expected to prevail throughout the remainder of the outlook period.

Here is this week's space weather and geophysical report, issued 2024 May 27 0142 UTC.

Highlights of Solar and Geomagnetic Activity 20 - 26 May 2024

Solar activity was at low to moderate levels during the period. Low levels were observed on 20, 25 and 26 May. Moderate (R1-Minor) levels were observed on 21-24 May. Region 3679 (S09, L=200, class/area Ekc/500 on 22 May) produced 10 M-class flares, the largest was an M4.2/1n event at 23/0216 UTC. Region 3689 (S08, L=098, class/area Dso/050 on 22 May) produced a single M-class flare on 23 May. No significant radio events were observed. No significant Earth-directed CMEs were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at low to normal levels.

Geomagnetic field activity ranged from mostly quiet to unsettled levels with a single active period observed late on 23 May. Unsettled to active periods were observed on 23-24 May due to negative CH HSS influence. Unsettled periods were observed late on 25 May through 26 May due to weak positive CH HSS influence. Total field readings approached 10 nT on 24-25 May with southward Bz readings to negative 10 nT late on 23 May. Solar wind readings were at a predominately steady 400 km/s throughout the period.

Forecast of Solar and Geomagnetic Activity 27 May - 22 June 2024

Solar activity is expected to be at a chance for moderate (R1-R2 / Minor-Moderate) levels due to the return of previous active region 3664 (S17, L=347).

There will be a slight chance of S1 (Minor) solar radiation storms from 28 May through 09 Jun upon the return of old region 3664.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at low to moderate levels.

Geomagnetic field activity is expected to be at unsettled to active levels on 27-28 May and 08-12 Jun due to the influence of positive polarity CH HSSs. Mostly quiet levels are expected on 29-31 May, 01-07 Jun and 13-22 Jun.
