SDF Number 142 Issued at 2200Z on 22 May 2011
IA.  Analysis of Solar Active Regions and Activity from  21/2100Z
to 22/2100Z:  Solar activity was very low.  All spotted regions on
the visible disk were small, magnetically simple and generally
quiescent.  New Region 1220 (N14W65) emerged today as a small
bipolar group.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low for the next three days (23-25 May) with a slight chance for a
C-class event on day one (23 May).
IIA.  Geophysical Activity Summary 21/2100Z to 22/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to remain predominantly quiet for the next three days.
