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 03 Dec 2006IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z Solar activity was low. Region 926 (S10W25) produced
two C1/Sf flares at 02/2207Z and 03/0325Z. This region remains a
beta-gamma group. Region 927 (N08W21) was quiet and stable.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low.
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field was quiet during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the first two days (4-5 December).
Predominantly quiet to unsettled conditions, with isolated active
periods, are expected on 6 December as a recurrent coronal hole
rotates into a geoeffective position.
