This is one of the strongest solar storms in ages. View from ISS is incredible.

Here is the less known open star cluster Collinder 470 is located in the Cocoon Nebula - IC 5146 in the constellation Swan. The Cocoon Nebula is a combination of emission, reflection and absorption nebulae. More recent theories say that the massive star BD + 46 ° 3474 in the centre of the nebula has provided transparency in the molecular cloud. This very beautiful and normally difficult object is located at the end of the dark nebula Barnard 168. The active star formation in the cloud leads to the formation of a young open star cluster called Collinder 470 with an estimated age of several hundred thousand years.

NGC 6826, also known as the Blinking Planetary Nebula or Caldwell 15, is a planetary nebula in the constellation Cygnus. It gets its nickname from the visual effect observed through telescopes: when looking directly at the central star, the surrounding nebula appears to fade or "blink" out of view, only to reappear when using averted vision. This is due to the bright central star overwhelming the eye's central vision, while the surrounding nebula is better seen with peripheral vision.
