Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 147 Issued at 2200Z on 26 May 2012
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity was low. A few nominal C-class flares
occurred during the period. A CME associated with a filament
eruption was observed in LASCO imagery off the southwest quadrant of
the solar disk, but does not appear to be Earth directed.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low for the next 3 days (27-29 May).
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels during the period.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be mostly quiet for the next 3 days (27-29 May).
