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 295 Issued at 2200Z on 22 Oct 2002IA. Analysis of Solar Active Regions and Activity from 21-2100Z to 22-2100Z Solar activity was at moderate levels. Region 162
(N27E22) produced an M1/Sf flare at 22/1535 UTC. Region 162
continues to grow and has developed a beta-gamma-delta magnetic
configuration in the trailing spot. Region 160 (S20W56) has shown a
decrease in area coverage and spot count in the past 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to be low
to moderate. Region 162 has M-class potential.
IIA. Geophysical Activity Summary 21-2100Z to 22-2100Z
The geomagnetic field was at quiet to unsettled levels. One period
on isolated active conditions was observed at 22/09-12 UTC. Solar
wind velocity continues to gradually decrease, ending the period
near 450 km/s.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled. Isolated active conditions are
possible on day one due to the M1/Type II event on 20 October.
