Geophysical 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 Solar and Geophysical Activity Summary
SGAS Number 004 Issued at 0245Z on 04 Jan 2003 This report is compiled from data received at SWO on 03 JanA. Energetic Events

B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was
predominantly quiet to unsettled. Isolated active to minor storm
conditions were observed between 03/1500 to 1800 UTC due to the
effects of a favorably positioned coronal hole. The greater than 2
MeV electron flux at geosynchronous orbit reached high levels during
the past 24 hours.
