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 336 Issued at 2200Z on 01 Dec 2008IA. Analysis of Solar Active Regions and Activity from 30-2100Z to 01-2100Z Solar activity was very low. No flares were observed.
The visible disk was spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 30-2100Z to 01-2100Z
Geomagnetic field activity was at quiet levels at all latitudes.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be at quiet levels during days 1 - 2 (02 - 03
December). Activity is expected to increase to quiet to unsettled
levels on day 3 (04 December) as a recurrent coronal hole high-speed
stream begins to disturb the field.
