Bulletin

Active solar conditions were observed since our last bulletin. An M6.4 flare occurred in NOAA AR 11936 on December 31 with peak time at 21:58 UT, associated with a CME. This eruption followed a long duration C8.8 event at 11:50 UT, occurring in the active region complex that is turning over the east limb. More C-class flaring is expected, especially in regions 11936 and 11938. Another M-class flare from AR 11936 is also possible. Due to the expected arrival of a coronal hole fast wind stream and CME activity, we expect minor storm conditions (K_Dourbes up to 5) late this evening and early tomorrow. SDO/AIA images show that the M-flare on December 31 was accompanied by a CME. Due to the location of the source region, we expect this slow CME (projected speed ~270 km/s) to reach Earth early on January 5 where it may cause unsettled or active geomagnetic conditions (K_Dourbes up to 4).

Today's estimated international sunspot number (ISN): 084, based on 10 stations.
