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.
