Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 044 Issued at 0245Z on 13 Feb 2003 This report is compiled from data received at SWO on 12 Feb
A. Energetic Events

B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet to unsettled levels. A single isolated active period was observed at higher latitudes between 12/1500 to 1800Z. The greater than 2 MeV electron fluxes at geosynchronous orbit reached high levels again today.
D. Stratwarm
STRATWARM ALERT/WEDNESDAY/STRATWARM EXISTS. IN THE MIDDLE AND UPPER STRATOSPHERE SLIGHTLY DISTURBED TEMPERATURE DISTRIBUTION WITH A WARM REGION OVER SIBERIA, LEADING TO A REVERSED TEMPERATURE GRADIENT BETWEEN 60N AND THE POLE FROM 5 TO 1 HPA
