Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 147 Issued at 2200Z on 27 May 2006
IA.  Analysis of Solar Active Regions and Activity from  26/2100Z
to 27/2100Z:  Solar activity was very low.  Region 885 (S12W54)
produced two B-class flares today.  The largest of these was a B7
flare at 27/1643Z.  Region 888 (N06W77) produced a B1 flare at
27/0723Z.  Region 889 (S03E12) was numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low, but there is a slight chance for a C-class flare.
IIA.  Geophysical Activity Summary 26/2100Z to 27/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet on 28 May.  Quiet to unsettled conditions are
expected on 29 May.  Mostly unsettled conditions, with isolated
active periods, are expected on 30 May due to transient effects.
