Solar activity report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 337 Issued at 2200Z on 03 Dec 2001IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z Solar activity has been moderate. The NOAA/SXI test
imagery observed an M2 event from Region 9714 at 02/2206 UTC as it
rotated around the southwest limb of the sun. Region 9715 (N04W49)
continues to show a slight decay from yesterday. New Region 9727
(S22E68) was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be low
to moderate. Isolated major flares are possible from Regions 9715
and 9718 (S07E03).
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled. Isolated active conditions are
possible for 04 - 05 December due to coronal hole effects.
