Another relatively quiet day when you consider the size of sunspot region 2192, the largest sunspot region that faced Earth in 24 years! Solar activity has been moderate today with only one M-class solar flare: M4.07 (R1-minor) at 07:48 UTC. This solar flare was rather impulsive but it was eruptive for a change and it did produce a coronal mass ejection! The bad news is that sunspot region 2192 miraculously managed to send the eruption south of the Sun-Earth line. No impact at Earth is thus expected from this event. In this article we take a closer look at the M4.0 solar flare and the evolution of sunspot region 2192.
