Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 057 Issued at 2200Z on 26 Feb 2010
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity was very low. No flares were detected.
Regions 1050 (S18W51) and 1051 (N15E41) remained quiet and stable.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low on day one (27 February). However, there is a chance for C-class
flares on days two and three (28 February - 01 March) due to the
return of old Region 1045 (N19, L251).
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
Geomagnetic field activity was at quiet levels.
IIB.  Geophysical Activity Forecast:  Geomagnetic field activity is
expected to be at quiet levels on day one (27 February). Activity is
expected to increase to quiet to unsettled levels on days two and
three (28 February - 01 March) due to a recurrent coronal hole
high-speed stream.
