A moderate solar flare reaching M1.3 erupted on May 10, 2013 peaking at 12:56 UTC. The source was returning Active Region 1726 which already produced M3.9 flare today making this the second M-class eruption of the day. This same region was the source of large prominence eruption and strong C-class solar flare yestarday at 23:15 UTC.
NOAA SWPC forecasters estimated 35% chance for M-class event, and 1% chance for an X-class event.
There are currently 9 numbered regions on the disk. Old Region 1726, the source of today's two M-class flares, is about to rotate into Earth's view, and will be named AR 1745. There is significant flaring from this region so it's one to watch for in the coming days. Beta-Gamma classified Region 1736, source of strong activity last week, is now located on the western limb and about to become far-side region. Region 1741 is located in the center of the disk today but still has, harmless, Alpha magnetic field. Regions 1742 and 1744 have Beta magnetic field and are about to rotate into the center of the disk.
