One of the biggest active regions of this solar cycle, AR 1944 (S08E38, Fkc/beta-gamma-delta), responsible for 6 M-class solar flares in last 4 days, is rotating into more geoeffective position.
The largest event it produced so far was a long
At 18:52 UTC today (January 1, 2014) strong solar flare measuring M9.9 erupted from Region 1936. R2 Moderate solar radiation storm was reported: area of impact centered primarily on sub-solar point on the sunlit side of Earth, limited blackout of HF
Geoeffective AR 1936 (S16W36, Eac/beta-gamma-delta) produced an M6.4 solar flare on Tuesday, December 31, 2013. The event started at 21:45 and peaked at 21:58 UTC. It is possible that Earth-directed CME was associated, a glancing blow to our planet is
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
Solar activity is picking up again. After M3.5 on December 19 at 23:19 UTC and M1.6 on December 20 at 11:57 UTC Sun unleashed more M-class flares today and it looks like it's going to continue.
Today, Region 1928 (S18W55, Ekc/beta-gamma) produced M1.9 at
Impulsive solar flare measuring M3.5 erupted on December 19 at 23:19 UTC. The source of the event was centered around new active region in close proximity to AR 1931 located on eastern limb.
This region is not yet in position to cause Earth directed
Moderate solar flare measuring M1.2 erupted today from around AR 1909. The event started at 07:17, peaked at 07:29 and ended at 07:49 UTC. Region 1909 (S17W50, Dso/beta) is decreasing in size but maintains some magnetic complexity.

After an impulsive M1.1 solar flare at 02:23 UTC today, a second M-class solar flare erupted from AR 1904 located around the west limb. The latest event peaked at 12:27 UTC as M1.0 solar flare. No Earth directed CMEs were observed.

An impulsive M1.1 solar flare was detected around departing Sunspot 1899 at 02:32 UTC on November 23, 2013. The source was actually a newly numbered Region 1904 (N12W60, Dai/beta-gamma). This region appeared to have enough of a separation in SDO HMI/Magnetogram imagery
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
