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 001 Issued at 2200Z on 01 Jan 2008IA. Analysis of Solar Active Regions and Activity from 31-2100Z to 01-2100Z Solar activity was low. Region 980 (S07E69) produced a
C1/Sf flare at 01/1537Z. As the region rotates onto the east limb,
its initial classification is a simple Axx alpha group.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low. There is a chance for an isolated M-class event from
Region 980.
IIA. Geophysical Activity Summary 31-2100Z to 01-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to remain quiet for the forecast period.
