Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 112 Issued at 2200Z on 22 Apr 2010
IA.  Analysis of Solar Active Regions and Activity from  21/2100Z
to 22/2100Z:  Solar activity was very low.  No flares were observed
during the last 24 hours.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
very low during the forecast period (23-25 April).
IIA.  Geophysical Activity Summary 21/2100Z to 22/2100Z:
The geomagnetic field was quiet during the last 24 hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field will be
predominately quiet with isolated unsettled conditions on day one
(23 April).  Quiet levels are expected for days two and three (24-25
April) as the effects of the coronal hole high speed stream
diminish.
