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 013 Issued at 2200Z on 13 Jan 2003IA. Analysis of Solar Active Regions and Activity from 12-2100Z to 13-2100Z Solar activity continued at low levels. A C4/Sf flare
and associated CME was observed near the SW limb at 13/1615Z. The
flare began in Region 242 (S07W87) with sympathetic flaring observed
soon after in Region 244 (S22W84). Region 242 is also the confirmed
source of yesterday's C6 event at 12/1425Z. A prominence erupted off
the east limb near N14 at around 1400Z. No significant changes were
noted in the remaining regions. New Region 257 (N16E23) was numbered
today.
IB. Solar Activity Forecast
Solar activity is expected to be low.
There is a chance for an isolated M-class flare.
IIA. Geophysical Activity Summary 12-2100Z to 13-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to continue at quiet to unsettled levels. Isolated active
periods are possible at higher latitudes.
