C1 solar flare and CME, glancing blow possible
A C1.2 solar flare took place today at 07:21 UTC and came from a sunspot region on the Sun's northern hemisphere. Sunspot region 2787 was to blame. While the solar flare wasn't that strong, it was eruptive and that's what counts! Associated with the solar flare were a coronal wave and coronal dimming.
