Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 057 Issued at 2200Z on 26 Feb 2006
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity has been very low.  Several low level
B-class events were observed from a region rotating onto the SE
limb.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.  An isolated C-class event is possible from the new oncoming
region.
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was primarily quiet with one period of
unsettled conditions observed at mid latitudes.  The greater than 2
MeV electron flux at geosynchronous orbit reached high levels today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be mostly quiet.  Isolated unsettled to active
conditions are possible on 28 February and 01 March due to a small
recurrent coronal hole.
