M1.0 solar flare from sunspot region 2443

Sunspot region 2443 has come to life once more with many C-class solar flares right now and it even managed to produce an impulsive M1.0 (R1) solar flare at 17:52 UTC. This event did not launch a coronal mass ejection.

This video using SDO footage shows the M-class solar flare:

A quick look at this sunspot region shows that new flux has emerged in the intermediate layout of this sunspot region during the past 12 hours with a solid amount of magnetic mixing there as well. At least two delta sunspots can now be found there and more M-class (R1-R2) activity can be expected.

M-class flare probability for the coming 24 hours: 65% chance
X-class flare probability for the coming 24 hours: 10% chance

Any mentioned solar flare in this article has a scaling factor applied by the Space Weather Prediction Center (SWPC), the reported solar flares are 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.
