Solar activity was low. There were three, low-level C-class flares during the past 24 hours, all from Region 1367 (S18W89). Region 1367 showed signs of new flux emerging as it was rotating around the west limb. Region 1374 (S18E01) continues to be the largest group on the disk (140 millionths) and shows a very small delta configuration in the leader spot region, but was quiet and stable. Two erupting prominences which led to coronal mass ejections were observed: the first just entered the LASCO/C2 field of view at 12/1848Z, slightly west of the north pole and the second entered LASCO/C2 field of view at 13/0200Z off the southwest limb. Neither of these CMEs are expected to be geoeffective.

Solar activity is expected to be low.

The geomagnetic field was mostly quiet. There was an interval of unsettled levels from 0900-1500Z at high latitudes.

The geomagnetic field is expected to be quiet for day one (14 December). Quiet levels with a chance for some unsettled periods are expected for day two (15 December) due to a possible brief, glancing blow from an erupting prominence/CME that was observed on 11 December. Quiet levels are expected to prevail for the third day (16 December).
