Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 334 Issued at 2200Z on 30 Nov 2002
IA.  Analysis of Solar Active Regions and Activity from  29/2100Z
to 30/2100Z:  Solar activity was very low during the past 24 hours.
Today's only flare activity was a B8/Sf at 1125 UTC from newly
numbered Region 209 (S20E62). Region 207 (S19E31) continues to be
the largest group on the disk but was quiet and stable. New Region
210 (S09W77) emerged during the past 24 hours.
IB.  Solar Activity Forecast:  Solar activity is expected to be low.
There is a slight chance for an M-class event from Region 207.
IIA.  Geophysical Activity Summary 29/2100Z to 30/2100Z:
The geomagnetic field was predominantly unsettled to active. Solar
wind speeds continue to be enhanced, and the Z-component of the
interplanetary magnetic field continues to hold at weakly negative
values. The solar wind signatures are consistent with a high speed
coronal hole driven solar wind stream. The greater than 2 MeV
electron fluxes reached high levels during the past 24 hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be unsettled to active during the next three days due to
continued effects from the high speed solar wind stream.
