M6.9 solar flare, sunspot regions 2241 and 2242
Solar activity reached high levels. Sunspot regions 2241 and 2242 are the dominate sunspot regions on the earth-facing disk and it is these two sunspot regions that produce all the activity right now. C-class solar flares are a common sight and we just saw a long duration M6.9 (R2-moderate) solar flare that peaked at 21:58 UTC. Can we expect more strong solar flares from these groups and will this M6.9 solar flare be eruptive?
