Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 026 Issued at 2200Z on 26 Jan 2011
IA. Analysis of Solar Active Regions and Activity from 25/2100Z
to 26/2100Z: Solar activity was at very low levels. Region 1149
(N17W77) produced occasional low-level B-class flares during the
period. Region 1149 continues to show decay in spot number. Region
1147 (N24W77) remained stable.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low. There is a slight chance for a C-class flare.
IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was at quiet levels.
