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 337 Issued at 2200Z on 02 Dec 2008IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z Solar activity was very low. No flares occurred during
the past 24 hours and the solar disk was void of spots.
IB. Solar Activity Forecast
Solar activity is expected to be very
low for the next three days (03-05 December).
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the first day (03 December). A gradual
increase to unsettled levels with a chance for active periods is
expected late on the second day (04 December) and lasting through
the third day (05 December) due to a high speed solar wind stream.
