SDF Number 143 Issued at 2200Z on 23 May 2006
IA.  Analysis of Solar Active Regions and Activity from  22/2100Z
to 23/2100Z:  Solar activity was very low. Today's activity consisted
of a few B-class events from Region 884 (S13W05) and Region 885
(S12E03). New region 886 (N08E46) emerged on the disk today.
IB.  Solar Activity Forecast:  Solar activity is expected to be
predominantly low. There is a chance for an isolated C-class event
during the next three days.
IIA.  Geophysical Activity Summary 22/2100Z to 23/2100Z:
The geomagnetic field was quiet to unsettled during the past 24
hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the next 24 hours (24 May). Mostly
unsettled conditions are expected for the second day (25 May) due to
recurrence. Conditions should return to quiet levels for the third
day (26 May).
