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 005 Issued at 2200Z on 05 Jan 2002IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z Solar activity was at moderate levels. Region 9773
(N13E52) produced an M1.9/1f flare at 05/1840 UTC and a number of
minor C-class flares. Region 9767 (S22W03) produced only C-class
flares and has remained mostly unchanged since yesterday,
maintaining a beta-gamma magnetic configuration.
IB. Solar Activity Forecast
Solar activity is expected to be low
to moderate. Region 9773 and Region 9767 have the potential for
M-class events.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field was quiet with one period at unsettled
conditions. The greater than 10 MeV proton event that started on
30/0245 UTC has ended at 04/2355 UTC.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled. A weak shock from the C5/1f
event on 03/0220 UTC is expected to arrive midday on day one of the
period and could produce slight disturbances.
