Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 005 Issued at 2200Z on 05 Jan 2002
IA.  Analysis of Solar Active Regions and Activity from  04/2100Z
to 05/2100Z:  Solar activity was at moderate levels.  Region 9773
(N13E52) produced an M1.9/1f flare at 05/1840 UTC and a number of
minor C-class flares.  Region 9767 (S22W03) produced only C-class
flares and has remained mostly unchanged since yesterday,
maintaining a beta-gamma magnetic configuration.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
to moderate.  Region 9773 and Region 9767 have the potential for
M-class events.
IIA.  Geophysical Activity Summary 04/2100Z to 05/2100Z:
The geomagnetic field was quiet with one period at unsettled
conditions.  The greater than 10 MeV proton event that started on
30/0245 UTC has ended at 04/2355 UTC.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled.  A weak shock from the C5/1f
event on 03/0220 UTC is expected to arrive midday on day one of the
period and could produce slight disturbances.
