Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 146 Issued at 2200Z on 26 May 2006
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity was very low.  Region 885 (S12W38)
produced a B5 flare at 25/2328Z.  A halo CME was observed in LASCO
imagery, beginning at 26/0006Z.  Regions 887 (S12E64) and 888
(N05W64) were numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was predominantly quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the next two days (27-28 May).  Unsettled
conditions, with isolated active periods, are expected on 29 May due
to transient effects from today's CME.
