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 336 Issued at 2200Z on 02 Dec 2010IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z Solar activity was very low during the past 24 hours.
New Region 1131 (N30E68) was numbered during the period and is an
Hsx-Alpha type spot group. Region 1130 (N14W52) remained stable and
quiet throughout the period.
IB. Solar Activity Forecast
Solar activity is expected to be very
low for the next three days (03-05 December) with a chance for
isolated C-class flares from Region 1130.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
The geomagnetic field was quiet during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled with a chance for isolated active
periods during the next three days (03-05 December) due to possible
effects from a CME associated with the disappearing filament
observed on 29 November. The CME observed near N15E40 on 30
November may also contribute to elevated activity throughout the
period.
