New active region producing M-class solar flares

A new sunspot region is now rotating into view and it is active. It already managed to produce three low-level M-class events (R1-minor) in just 24 hours. It started yesterday with an M1.1 solar flare and this morning it produced an M3.0 solar flare at 04:57 UTC and a very long duration M1.5 solar flare a 08:15 UTC.

Coronagraph imagery is limited but all three of these events seem to have produced coronal mass ejections. They are of course not yet earth-directed due to this sunspot region's location on the east limb but it is great news that this sunspot region seems to be capable of producing eruptive solar flares.

Some sunspots are now rotating into view but we can not tell much about the sunspot region just yet. We will get a better look at this sunspot region in the next 24 hours as it rotates into view. This will enable us to see it's magnetic layout and judge it's flaring potential. It is however already a good sign that it managed to produce three M-class solar flares in such a short ammount of time. Are we in for a period of enhanced solar activity? It's about time!

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.
