Solar activity reached high levels thanks to two M5 class solar flares since our last update. These solar flares came from the only numbered sunspot region on the Earth-facing disk: sunspot region 2297. The first of these solar flares was a long duration M5.8 solar flare that peaked yesterday at 23:53 UTC and the second one was a more impulsive M5.1 solar flare peaking today at 03:24 UTC.
