Sunspot region 3664, major flares and CMEs!
What a day! Sunspot region 3664 and 3668 have merged into a very complex sunspot cluster which has been producing a ton of M-class activity and even two X1 events. The first of these two X-class solar flares was unremarkable but the second X1 solar flare produced a coronal mass ejection with an earth-directed component but more on that later. We are also going to take a look at an M-class event which also produced a coronal mass ejection. A lot to go over today!
