Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 067 Issued at 0245Z on 08 Mar 2002 This report is compiled from data received at SWO on 07 Mar
A. Energetic Events
Begin  Max  End  Rgn   Loc   Xray  Op 245MHz 10cm   Sweep
1748 1755 1808              C2.5     160
2046 2104 2129              C6.3     150
B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field activity was at quiet to active levels. An isolated minor storm condition was observed at Fredericksburg at 06/2100 UTC, believed to be a result of a large, transequatorial coronal hole during it's waning stage. The greater than 2 MeV electron flux at geosynchronous orbit has been elevated throughout the period following the passage of the high speed stream.
D. Stratwarm
STRATWARM ALERT EXISTS STRATWARM THURSDAY IN THE MIDDLE AND UPPER STRATOSPHERE, STILL DISTURBED CONDITIONS AFTER THE WARMING. STILL A REVERSED TEMPERATURE GRADIENT AT 10HPA, BUT FURTHER RETURNING TO NORMAL CONDITIONS. END OF THIS ALERT PERIOD.
