Two coronal mass ejections, G3 storm watch
What an exciting two days we are having, sunspot regions 2978 and especially 2975 are really delivering with the latter group producing countless of C-class solar flares and even a couple of M-class solar flares. Yesterday's M4.0 solar flare of course being the strongest thus far. This M4.0 solar flare and a smaller M1 solar flare launched two coronal mass ejections into space, both of which have an earth-directed component. Sunspot region 2975 remains a very complex Beta-Gamma-Delta sunspot region which is capable of more M-class activity, and perhaps even a low X-class flare.
