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 010 Issued at 2200Z on 10 Jan 2003IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity has been low. Only C-class events were
observed through the period. Region 242 (S08W48) has shown a
decrease in area and sunspots but retains its beta gamma magnetic
configuration. Region 247 (S15E20) has maintained its area and spot
count and the magnetic configuration of the region became a beta
gamma configuration. Region 251 (S13E44) has an area of 340
millionths of white light with 12 spots and a beta configuration.
Two new regions were numbered today as Region 253 (N11W36) and 254
(S15E72).
IB. Solar Activity Forecast
Solar activity is expected to be low
to moderate. Isolated M-class events are possible from Region 242,
247, and 251.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field has been quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to remain quiet to unsettled for the next three days.
