Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 054 Issued at 2200Z on 23 Feb 2010
IA.  Analysis of Solar Active Regions and Activity from  22/2100Z
to 23/2100Z:  Solar activity was very low. Region 1049 (S18W78)
produced isolated low-level B-class flares as it approached the west
limb. A new Bxo/Beta spot group emerged midway through the period
and was numbered as Region 1050.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low through the period.
IIA.  Geophysical Activity Summary 22/2100Z to 23/2100Z:
