Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 007 Issued at 2200Z on 07 Jan 2001
IA.  Analysis of Solar Active Regions and Activity from  06/2100Z
to 07/2100Z:  Solar activity was low. The most impressive event of
the period was a CME launched from beyond the NW limb at about 0400
UTC. An H-alpha filament disappeared in conjunction with the
eruption. The largest flare was a C5 x-ray event associated with
Region 9302 (N20E39) at 06/2350 UTC. The event was seen in the EIT
imagery from SOHO. Two new regions, 9304 (N11E58) and 9305 (S07E64)
were assigned, bringing the number of spotted regions to 13.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
to moderate.
IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled.
