We are still excited following yesterday's X-class solar flare from sunspot region 2158 but there is another sunspot region that is demanding our attention: a new sunspot region on the eastern limb produced an M2.13 (R1-minor radio blackout) solar flare that peaked at 15:26 UTC and just now an impulsive M1.41 (R1-minor radio blackout) solar flare that peaked at 21:26 UTC. Image: the M2.1 solar flare as seen by NASA SDO.
The solar flares were impulsive in nature (short duration) and will likely not produce a Coronal Mass Ejection. Even if it does release a CME it will be directed away from Earth as the solar flare occured behind the eastern limb. STEREO footage reveals that this group might be the return of old sunspot region 2146.
Everyone's focus of course remains on sunspot regions 2157 and 2158 who are directly facing Earth. Both regions seem to slowly decay but both regions remain capable of producing an isolated M-class event. However, it does seem that there might be a new region coming in that could continue the high solar activity even when sunspot regions 2157 and 2158 disappear.
