Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 074 Issued at 0245Z on 15 Mar 2001 This report is compiled from data received at SWO on 14 Mar

B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to unsettled.
D. Stratwarm
stratwarm alert/wednesday/stratwarm exists. 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 vortex weakens. slow transitions to summer conditions most probable.
