First M-class solar flare of a Solar Cycle 25 region!

925 days. That is the amount of time we had to wait since we last saw a M-class solar flare on the Sun. But today the wait is over. An impulsive M1.19 solar flare (minor R1 radio blackout) took place on our Sun this morning peaking at 07:24 UTC. NASA's Solar Dynamics Observatory seems to have taken a break from its sun-watching duty for some reason but STEREO Ahead captured the impulsive eruption confirming it comes from a sunspot region near the east limb from Earth's point of view. This sunspot region very likely belongs to Solar Cycle 25 due to its high latitude and it could even be the first M-class solar flare of Solar Cycle 25 depending on if we have passed solar minimum or not.
