M8.7 coronal mass ejection, sunspot region 2241 & 2242
Solar activity today is at high levels thanks to the M8.7 solar flare that occurred this morning at 04:51 UTC. For more information regarding this solar flare we advice you to read the article that we posted this morning. Coronagraph imagery from SOHO is now complete and shows that this solar flare indeed launched a coronal mass ejection.
M8.7 solar flare from sunspot region 2242
Solar activity increased to high levels thanks to sunspot region 2242, which continues to develop and gain in magnetic complexity. It produced a long duration M8.75 (R2-moderate) solar flare that peaked at 04:51 UTC which was surprisingly already the third M-class solar flare of today.
