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 043 Issued at 2200Z on 12 Feb 2002IA. Analysis of Solar Active Regions and Activity from 11-2100Z to 12-2100Z Solar activity was low. There were several C-class
events during the period. The largest of these was an C5/1f long
duration flare at 12/1442 UTC from Region 9825 (N13E29). This
region continues to develop in area and magnetic complexity and is
currently an Eai beta-gamma group.
IB. Solar Activity Forecast
Solar activity is expected to be low
to moderate. Region 9825 has the potential to produce an isolated
M-class flare.
IIA. Geophysical Activity Summary 11-2100Z to 12-2100Z
The geomagnetic field has been quiet to unsettled. The greater than
2 MeV electrons at geosynchronous orbit were enhanced to moderate
levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled.
