Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 019 Issued at 2200Z on 19 Jan 2001
IA.  Analysis of Solar Active Regions and Activity from  18/2100Z
to 19/2100Z:  Solar activity has been moderate.  A long duration
M1/Sf flare occurred in Region 9313 (S07E57), max at 19/1710 UTC. 
This event consisted of several eruptive centers that brightened at
various times over the duration of the flare.  A small filament in
this region was also reported active during the event and a CME was
observed.  Several new regions were numbered:  Region  9315
(S28E44), Region 9316 (S17E75), and Region 9317 (N08W72).
IB.  Solar Activity Forecast:  Solar activity is expected to be low
to moderate.  Isolated M class events are possible.
IIA.  Geophysical Activity Summary 18/2100Z to 19/2100Z:
The geomagnetic field has been quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to remain quiet.
