X1.1 solar flare
After a fairly quiet start of the month the Sun has really started to pick up the pace again. The past few days we have had numerous M-class solar flares from many different sunspot regions. Some of these launched minor coronal mass ejections but most of the time the flares were too impulsive or the resulting coronal mass ejections just weren't aimed at Earth.
