IA.  Analysis of Solar Active Regions and Activity from  23/2100Z
to 24/2100Z:  Solar activity was at very low levels for the past 24
hours. Region 1057 (N17E57) has showed steady growth throughout the
day and is classified as a D type group. The total sunspot area 
increased to about 240 millionths in size near the end of the
period. Region 1056 (N17W50) decayed to spotless plage. No new
regions were numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to be at
very low to low levels with C-class flares likely from Region 1057.  There
is a slight chance for M-class events also from Region 1057.
IIA.  Geophysical Activity Summary 23/2100Z to 24/2100Z:
The geomagnetic field has been at quiet levels for the past 24 hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet to unsettled levels for the next two days
(25-26 March) due to the arrival of a weak coronal hole high-speed
stream. The geomagnetic field is expected to return to quiet levels
on day three (27 March) as the effects of the coronal hole subside.
