A moderate M1.2 solar flare was detected around sunspot 1893 at 11:11 UTC on November 21, 2013. This active region is now located behind the west limb, so any subsequent coronal mass ejections (CMEs) would be too far west to impact Earth. This same region is responsible for an X1.0 flare from November 19, 2013.

Sunspots 1895 and 1897 continue to rotate towards the southwest limb. There are currently five numbered sunspots. Active Region 1899, located at the center of visible solar disk, remains the biggest one. NOAA/SWPC forecasters estimate 20% chance for M-class and 1% chance for X-class solar flares in the next 24 hours.
