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 024 Issued at 2200Z on 24 Jan 2011IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z Solar activity was at low levels. Region 1149 (N16W45)
produced a C1 flare at 24/0615Z. Region 1149 is currently a Dsi-beta
group, with a significant drop in spot count. Region 1147 (N24W49)
produced a few low-level B-class flares and remains an Hsx-alpha
group.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low, with a slight chance for an isolated M-class flare.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
The geomagnetic field was at quiet levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet levels, with isolated unsettled levels
possible at high latitudes, for the next three days (25-27 January).
