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 Dec
A. Energetic Events
Begin  Max  End  Rgn   Loc   Xray  Op 245MHz 10cm   Sweep
1520 1524 1526  0231 S25W31 C1.6  Sf 260
B. Proton 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.
