C5.0 solar flare
A sign of life from our star! Sunspot region 2733 erupted with a C5.0 solar flare today at 13:22 UTC. While not the kind of solar fireworks like M or X-class solar flares, this is a fairly decent solar flare during solar minimum. In fact, this is the strongest solar flare since a C4 class solar flare that took place on 30/03/2018.
