Flaring activity is at the same level as the previous days: the base X-ray radiation curve is situated near the bottom of the C-level. The active region which is contributed the highest probability to flare is NOAA AR1917. The region in the northern hemisphere which rotates over the east limb (but has no NOAA NR yet) is also in the running to produce C-flares.
The shock arrival of yesterday December 8 didn’t cause any geomagnetic disturbance. The co-rotating interaction region (arrival on December 7) and the associated fast solar wind dominated the solar wind data. The result was a geomagnetic storm of Kp=6 early December 8.
The mass ejection that was associated with the M1.2 flare peaking at 7:29UT on December 7 might cause a glancing blow late today (December 9) or tomorrow (December 10).
