Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 055 Issued at 2200Z on 24 Feb 2010
IA.  Analysis of Solar Active Regions and Activity from  23/2100Z
to 24/2100Z:  Solar activity was very low. Region 1049 (S19W91)
produced an isolated B-class flare as it rotated out of view. New
Region 1051 (N17E66), a Cso/Beta group, also produced isolated
B-class flares during the period. LASCO C2 images indicated a halo
CME, first visible at 24/0354Z, with a plane of sky velocity of
approximately 380 km/sec. The CME was determined to be a backside
event.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low through the period with a slight chance for a C-class flare from
Region 1051.
IIA.  Geophysical Activity Summary 23/2100Z to 24/2100Z:
Geomagnetic field activity was at quiet to unsettled levels.
Unsettled levels were observed during 24/0300 - 0600Z.
IIB.  Geophysical Activity Forecast:  Geomagnetic field activity is
expected to be at quiet levels through the period (25 - 27
February).
