M-class solar flare, elevated EPAM levels
Solar activity reached moderate levels today for the first time since 16 November 2014, all thanks to an M1.8 solar flare at 06:41 UTC from sunspot region 2222. We also see enhanced proton and electron levels as measured by ACE EPAM. In this article we will try to find out what is causing this. Could there be a coronal mass ejection heading towards Earth or is there one arriving right now?
