Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 078 Issued at 2200Z on 19 Mar 2010
IA.  Analysis of Solar Active Regions and Activity from  18/2100Z
to 19/2100Z:  Solar activity was very low. Region 1054 (N16W69)
produced the largest event of the period, a B7/sf flare, at
18/2308Z.  An associated Type II radio sweep was observed by Palehua
and Learmonth radio observatories at 18/2311Z.  Palehua reported a
speed of 776km/s.  SOHO LASCO C2 depicted a weak, west limb CME. 
Region 1056 (N18E22) remains stable and quiet.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
very low with only a slight chance for a C-class flare within the
next 3 days (20-22 March).
IIA.  Geophysical Activity Summary 18/2100Z to 19/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the next 3 days (20-22 March).
