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 2007

IA. Analysis of Solar Active Regions and Activity from 22-2100Z to 23-2100Z

Solar activity was very low. Region 939 (S03W55) has changed little since yesterday and continues to produce small B-class flares.
IB. Solar Activity Forecast
Solar activity is expected to be very low to low. C-class flares are possible in Region 939.
IIA. Geophysical Activity Summary 22-2100Z to 23-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit was high.
