Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 120 Issued at 0245Z on 30 Apr 2003 This report is compiled from data received at SWO on 29 Apr
A. Energetic Events
Begin  Max  End  Rgn   Loc   Xray  Op 245MHz 10cm   Sweep

B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet to minor storm levels. Solar wind velocity remains elevated near 550 km/s. Transient flow has produced periods of southward Bz that resulted in isolated active and minor storm conditions.
D. Stratwarm
None
