Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 072 Issued at 0245Z on 13 Mar 2001 This report is compiled from data received at SWO on 12 Mar
A. Energetic Events
Begin  Max  End  Rgn   Loc   Xray  Op 245MHz 10cm   Sweep
None
B. Proton Events
None
C. Geomagnetic Activity Summary
Quiet to unsettled with an isolated active period during 12/1500 - 1800 UTC.
D. Stratwarm
Stratwarm alert exists Monday As a result of the major warming, the circulation in the lower stratosphere remains further disturbed leading to a reversed temperature gradient up to 20 hpa. In the middle and upper stratosphere, the cold and elongated polar vortex weakens. Slow transition to summer conditions most probable.
