Moderate M3.1 solar flare erupted from AR 1936 located at the center of the disk


Moderate solar flare reaching M3.1 erupted from beta-gamma Region 1936 on December 29 at 07:56 UTC. Region 1936 is located at the center of the disk, it is in almost perfect geoeffective position and is currently the only flaring region on Earth side of the Sun. Any CME from this region would be Earth directed. Click here to see the video of M3.1 event.

NOAA SWPC forecasters estimated 25% chance for M-class, and 1% chance for X-class solar flare today.

Yesterday, Region 1934 (see image below) indicated growth in the intermediate portion of the region with a weak delta apparent in the leader spot. Region 1936 maintained a weak mix of polarities in its trailer portion. Minor consolidation and penumbral growth was noted in the leader portion with an overall increase in region spot count.

There are currently 5 active sunspot regions on the Earth side of the Sun.
