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 026 Issued at 2200Z on 26 Jan 2002IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z
Solar activity was moderate. New Region 9802 (S13E72)
produced an M1/Sf flare at 26/2005 UTC. This active region does not
appear particularly large or complex. Region 9787 (S09W33) remains
the largest group but has been relatively quiet.
IB. Solar Activity Forecast
Solar activity is expected to be low
to moderate.
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
The geomagnetic field was quiet to active.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled.
