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 013 Issued at 2200Z on 13 Jan 2009IA. Analysis of Solar Active Regions and Activity from 12-2100Z to 13-2100Z Solar activity was very low. The only region on the
visible disk is Region 1010 (N18W20) which has been quiet as it
experienced slow decay.
IB. Solar Activity Forecast
Solar activity is expected to be very
low. There is a slight chance for a C-class flare from Region 1010.
IIA. Geophysical Activity Summary 12-2100Z to 13-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be predominately quiet for the next three days (14 - 16
January).
