Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 283 Issued at 0245Z on 10 Oct 2001 This report is compiled from data received at SWO on 09 Oct
A. Energetic Events
Begin  Max  End  Rgn   Loc   Xray  Op 245MHz 10cm   Sweep
0724 0741 0750  9657 N19E67 C7.0  Sf 125    12     II
1046 1113 1149  9653 S28E08 M1.4  2f 25     130    II/IV
B. Proton Events
The greater than 10 MeV proton flux at geosynchronous orbit remained at elevated levels but below the proton event threshold of 10 pfu.
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet to active levels. High speed stream effects are believed to be responsible for the elevated field levels.
