Joint USAF/NOAA Solar and Geophysical Activity Summary
SGAS Number 189 Issued at 0245Z on 08 Jul 2002
This report is compiled from data received at SWO on 07 Jul
A. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep
0334 0401 0427 C3.5 1800 53

B. Proton Events: None
C. Geomagnetic Activity Summary: The geomagnetic field was
predominantly quiet to unsettled, with one isolated active period
observed at Boulder during 07/1500-1800 UTC. Coronal hole effects
appeared to wane throughout the day. A 10 MeV proton event began at
07/1830 UTC and remains in progress. Maximum flux observed thus far
was 22 pfu at 07/1955 UTC.
D. Stratwarm: None
