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 005 Issued at 2200Z on 05 Jan 2003IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z Solar activity was at low levels. Region 243 (S19W60)
produced the largest flare of the period, a C5.8/Sf event occurring
at 05/0617 UTC. Regions 242 (S08E20) and 244 (S23E27) were
responsible for several low level B and C-class flares during the
period. All three of these regions slowed from previous days growth
trend with little change noted in areal spot coverage or magnetic
complexity during the period. A 23 degree disappearing solar
filament began to erupt at approximately 05 0900 UTC with an
associated CME that does not appear to have an earth-bound
trajectory. A bright surge just beyond the east limb (with a radial
vector of .26 degrees) occurred at 05/0727 UTC which is believed to
be old returning region 226. No new regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be at
low levels. Region 242 has a very slight chance of producing a low
level M-class event.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field was at quiet to unsettled levels. The greater
than 2 MeV electron flux at geosynchronous orbit reached moderate
levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled levels.
