There are currently 7 sunspot regions visible on the solar disk. Six low-level C-class flares were recorded over the observing period. NOAA 2248 produced the strongest flare (C3.3 peaking at 17:59UT). This group has some magnetic polarity mixing, just like NOAA 2251 which is also gradually increasing its sunspot area. The greater than 10 MeV proton flux gradually increased and was slighly enhanced starting from 15:00UT. With values just below 1 pfu (21:00-24:00UT), the maximum proton flux remained well below the event threshold. A 35-degrees long, but currently stable filament is visible in the northeast solar quadrant. Further C-class flaring is expected. Solar wind speed was fluctuating between 360 and 390 km/s until about 18:00UT, when it gradually started to increase to values averaging 570 km/s around 09:30UT. Initially (15:00-22:00UT), Bz fluctuated wildly between -10 and +10 nT. After midnight, the fluctuations attenuated to values between -5 and +7 nT. Active geomagnetic conditions were recorded (Kp=4), with locally brief periods of minor geomagnetic storming (Dourbes: K=5 at 20:00UT). The source of this high speed stream (HSS) is a coronal hole that passed the CM on 22-23 December. Unsettled geomagnetic conditions are expected, with an active period possible in the wake of the HSS. After that, quiet to unsettled conditions are expected to resume.
