Big sunspot region 2665 (beta) erupted with an impulsive solar flare measuring M1.3 at its peak time on July 9, 2017. The event started at 03:09, peaked at 03:18 and ended at 03:37 UTC. The last time our star unleashed an M-class solar flare was on July 4, 2017....
July 09, 2017
Solar activity was at moderate levels on July 3, 2017, with 14 B-class and one impulsive M1.3 solar flare observed at 16:15 UTC. The M-class event started at 15:37 and ended at 16:18 UTC. The last time our star unleashed an M-class solar flare was on April 3, 2017....
