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 025 Issued at 2200Z on 25 Jan 2010IA. Analysis of Solar Active Regions and Activity from 24-2100Z to 25-2100Z Solar activity was very low. No flares occurred during
the past 24 hours. Region 1041 (S23E13) showed a slight increase in
the number of spots. Region 1042 (N18W71) was quiet and stable,
IB. Solar Activity Forecast
Solar activity is generally expected
to be very low. There is a chance for an isolated C-class event
during the next three days (26-28 January) from either Region 1041
or 1042.
