Solar activity is at high levels as our Sun continues to produce numerous M-class events. Both sunspot region 2422 and 2423 are to blame, with sunspot region 2422 being the most active and the most complex of these sunspot regions. None of these events launched an earth-directed coronal mass ejection.
As sunspot region 2422 is facing Earth right now, it is by far the most interesting sunspot region on the earth-facing disk. Let's focus our attention on this region:
Compared to yesterday, we have to conclude that there has been some magnetic separation between the leading and trailing sunspot clusters but when we look at the delta sunspots we see that this region gained some serious magnetic complexity which will guarantee more M-class solar flares.
While there remains a small delta sunspot near the leading sunspot cluster, we see that there is one large delta sunspot surrounded by many tiny spots that have an opposite polarity. We have seen a flurry of low-level M-class activity but this structure could harbor massive magnetic tension which has the potential to let loose a strong M-class (R2) or even an X-class (R3) event.
