Joint USAF/NOAA Solar and Geophysical Activity Summary
SGAS Number 096 Issued at 0245Z on 06 Apr 2002
This report is compiled from data received at SWO on 05 Apr
A. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep
0453 0457 0458 C1.9 250

B. Proton Events: None
C. Geomagnetic Activity Summary: The geomagnetic field was
predominantly quiet, with an isolated unsettled period observed at
higher latitudes during 05/1800-2100 UTC. The greater than 2 MeV
electron flux observed at geosynchronous orbit exceeded event
threshold again today.
D. Stratwarm: None
