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 342 Issued at 2200Z on 08 Dec 2005IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z Solar activity was low. A C1 flare occurred at 08/1902
UTC from a new region just beyond the east limb near N19E90. Both
Regions 826 (S06W80) and 830 (N12W01) produced small B-class flares.
New Region 832 (S14W61) emerged on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low.
C-class activity is possible in Regions 826 and 830 as well as the
new region rotating onto the disk near N19E90.
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit was high.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled.
