Surprise surprise! Sunspot region 2816 produced an M1.1 solar flare which peaked at 23:42 UTC. This is the first M-class solar flare since 29 November and the third M-class solar flare of Solar Cycle 25 thus far. Our Sun decided to wake up as we now all of a sudden have three numbered sunspot regions on the earth-facing solar disk.
