Sunspot region 2644 was again the most active sunspot region on the earth-facing solar disk today. It produced two M-clas solar flares today: an M1.2 solar flare (R1-minor) at 01:05 UTC and an M5.8 solar flare (R2-moderate) that peaked at 14:29 UTC. The M5.8 solar flare is this region's third solar flare that peaked above the M5 threshold and the strongest solar flare produced by sunspot region 2644 thus far.
Solar activity was at high levels yesterday (2 April 2017) as our Sun produced four M-class solar flares! The strongest of these solar flares was an M5.7 solar flare (R2-moderate) that peaked at 20:33 UTC.
A lot of people come to SpaceWeatherLive to follow the Solar activity or if there is a chance to see the aurora, but with more traffic comes higher costs to keep the servers online.
