M3.9 solar flare, S1 radiation storm
M-class flaring continues today from sunspot region 2975 with an M2.9 solar flare this night and a spectacular long duration M3.9 solar flare at 13:55 UTC. While writing this news article, we see yet another M-class flare from this region peaking at M4.3 but this solar flare looks much more impulsive and might not release a CME, but it is still way too early to tell.
