Bülletään

The flaring activity in the southern solar hemisphere continues at C-class level. The largest flare in the past day was a C5.6 flare originating in NOAA AR 11936 with peak time at 02:40 UT today. Afterwards, also NOAA AR 11938 produced a C2.0 flare, peaking at 05:32 UT. Both regions are expected to produce more C-flares in the coming hours. AR 11936, which has evolved to a beta-gamma-delta region, also has the potential to produce an M-class flare. We maintain the warning condition for proton events. STEREO-A/COR2 images show a CME at 07:08 UT, after a data gap. More data is needed for further analysis, but this event may originate near NOAA AR 11934, which is turning over the west limb. A possible glancing blow from this CME can occur late on January 3. STEREO-B/COR2 observed a faint CME on December 29 around 20:25 UT, possibly linked to the M-flare on that day. A glancing blow from this CME is possible on January 2. We expect minor geomagnetic storm conditions late on January 1 and early on January 2 (K_Dourbes up to 5) due to the arrival of a fast coronal hole wind stream and possible effects from the CME activity on December 29.
