Updated Feb 23 2200 UTC Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 054 Issued at 2200Z on 23 Feb 2012 IA. Analysis of Solar Active Regions and Activity from 22/2100Z to 23/2100Z: Solar activity was very low. Region 1422 (N15W52) showed decay in its trailing spots. A new region appeared on the NE limb and was numbered Region 1423 (N18E70). Two CMEs were observed overnight; the first off the North limb, observed in LASCO C2 imagery beginning at approximately 23/0148Z and the second beginning at 23/0824Z off the NW limb. The second CME was associated with a filament eruption on the NW limb first seen in SDO/AIA 193 imagery at 23/0746Z. None of the CMEs are expected to be geoeffective. IB. Solar Activity Forecast: Solar activity is expected to be at very low levels with a chance for a C-class activity. IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z: The geomagnetic field was quiet. Solar wind speed at the ACE spacecraft decreased from approximately 530 km/s to 440 km/s while the Bz component of the Interplanetary Magnetic Field did not vary much beyond +/- 4 nT. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to continue at mostly quiet conditions for the forecast period (24 - 26 February).
