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 358 Issued at 0245Z on 24 Dec 2002 This report is compiled from data received at SWO on 23 DecA. Energetic Events

None
C. Geomagnetic Activity Summary
The geomagnetic field was at
unsettled to minor storm levels. Sustained southward Bz and a
six-hour period of elevated solar wind velocity (peak velocity 600
km/s) resulted in active conditions at mid-latitudes and minor storm
conditions on the planetary index.
