Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 073 Issued at 2200Z on 14 Mar 2001
IA.  Analysis of Solar Active Regions and Activity from  13/2100Z
to 14/2100Z:  Solar activity was very low. The largest x-ray flare of
the past day was a B9 at 14/1211 UTC. No optical flare reports were
received for this particular event. Region 9373 (S08E07) remains the
largest and most complex area on the visible disk and has changed
little since yesterday. New Regions 9382 (N09W74), 9383 (S09W44),
and 9384 (N10E02) were numbered.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low. Region 9373 is the most likely source of activity,
including the possibility of an isolated M-class event.
IIA.  Geophysical Activity Summary 13/2100Z to 14/2100Z:
The geomagnetic field was quiet to unsettled.
