Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 234 Issued at 2200Z on 22 Aug 2010
IA.  Analysis of Solar Active Regions and Activity from  21/2100Z
to 22/2100Z:  Solar activity has been at very low levels for the past
24 hours. No flares were observed during the period and no new
regions were numbered.
IB.  Solar Activity Forecast:  Solar activity is expected to be at
very low levels for the next three days (23-25 August).
IIA.  Geophysical Activity Summary 21/2100Z to 22/2100Z:
The geomagnetic field has been at quiet levels for the past 24 hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet levels on day one (23 August),  at quiet to
unsettled levels on day two,(24 August), and unsettled to active
levels with a chance for isolated minor storm periods on day three
(25 August). This increase in activity is due to the arrival of a
recurrent coronal hole high-speed stream.
