#ar3664

It’s still there, it’s approaching this side of the Sun again, and it’s kicking up a significant stink. The image below is from yesterday.

“Yesterday, it announced its return with an X2.8-class solar flare. Amateur astronomer Michael Karrer was watching the sun when the explosion occurred, and he captured [the above] picture of flying debris… “I have not seen an explosion like this in my 40 years of observing the sun," says Karrer. "So fast, so far out into space! It was gigantic." The explosion caused a deep shortwave radio blackout over east Asia and hurled a bright CME into space. A NASA model of the CME confirms that it will miss Mercury, Venus and Earth. None of the inner planets will be affected by this powerful event.

AR3664 just will not quit.

Mancha solar del ancho de 15 Tierras entra en erupción y lanza colosal llamarada solar clase X

AR3664 no es una mancha solar cualquiera. Posee el ancho de 15 planetas Tierra y ha entrado en…

Sunspot #AR3664 has grown so large, it is now visually rivaling the great #Carrington sunspot of Sept. 1859. To illustrate their similarity, Carrington's famous sketch (to scale) has been added to a picture of today's sun:

"How big is AR3664? Sprawling almost 200,000 km from end to end, it is 15 times wider than Earth. You can see AR3664 through ordinary eclipse glasses with no magnification at all. Moreover, it is easy to project an image of this sunspot onto the sidewalk or a white screen just as Carrington did in the 19th century.
