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 2002IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z Solar activity was low. Region 208 (N11E22) produced
the largest event of the period, an impulsive C8/Sn flare at 03/0818
UTC. This region has declined in penumbral area but retains
moderate magnetic complexity. Region 207 (S19W06) produced a few
B-class events over the course of the day. New Region 213 (N15E79)
rotated into view and was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be
predominantly low, with a chance for isolated moderate flare
activity during the next three days. Region 208 is a possible
source of low level M-class flare activity.
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field was quiet to unsettled. Greater than 2 MeV
electron flux at geosynchronous orbit reached high levels again for
the fifth consecutive day.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mainly quiet to unsettled for the forecast period.
Greater than 2 MeV electron flux at geosynchronous orbit may persist
at high levels for the next one to two days.
