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 023 Issued at 2200Z on 23 Jan 2010IA. Analysis of Solar Active Regions and Activity from 22-2100Z to 23-2100Z Solar activity has been at very low levels for the past
24 hours. Isolated low level B-flares were observed. Region 1041
(S24E35) is now classified as a Eai-beta with 9 spots. Region 1042
(N22W42) is now classified as a Cao-beta with 11 spots. No new
regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to remain
at very low to low levels with a slight chance for an isolated
M-flare.
IIA. Geophysical Activity Summary 22-2100Z to 23-2100Z
The geomagnetic field was predominantly quiet for the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to remain at quiet levels for the next three days (24-26
January).
