Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 238 Issued at 2200Z on 26 Aug 2010
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity was very low during the past 24 hours.
Region 1101 (N13E48) produced two low level B-class flares.
IB.  Solar Activity Forecast:  Solar activity is forecast to be very
low for the next 3 days (27-29 August).
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field ranged between quiet and active conditions
during the past 24 hours.  The greater than 2 MeV electron flux at
geosynchronous orbit was high throughout the period.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
forecast to be mostly quiet to unsettled with isolated active
conditions on day 1 (27 August), returning to mostly quiet
conditions on days 2 and 3 (28-29 August).
