Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 148 Issued at 2200Z on 28 May 2006
IA.  Analysis of Solar Active Regions and Activity from  27/2100Z
to 28/2100Z:  Solar activity was very low.  New region 890 (S14W29)
produced a B1 flare at 28/1257Z.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 27/2100Z to 28/2100Z:
The geomagnetic field was mostly quiet.  A period of unsettled
conditions was observed from 28/0300Z - 28/0600Z, possibly due to a
glancing blow from the CME which occurred on 26 May.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled for the first two days (29-30
May).  Predominantly unsettled conditions are expected on 31 May.
