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 2003

IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z

Solar activity was at moderate levels. An isolated M1 flare was observed at S19 on the southwest limb at 02/2300Z. The majority of activity over the past twenty-four hours has been from the southwest limb with two active latitudes; S13 and S19. A C2 flare occurred at S13 on the west limb at 03/2008Z. Region 517 (S06E34) appears to have entered a decay phase with a decrease in area coverage down to 210 millionths. New Region 518 (S22E10) was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be at low levels. Isolated moderate level activity is possible from the southwest limb.
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field was at quiet levels. The greater than 10 MeV proton event that began on 02 December at 1505Z is still in progress. Up to this point, peak flux levels have reached 86 pfu at 02/1730Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to active levels. Coronal hole high speed stream effects are expected to produce active conditions on 04-05 December.
