Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 073 Issued at 0245Z on 14 Mar 2001 This report is compiled from data received at SWO on 13 Mar
A. Energetic Events
Begin  Max  End  Rgn   Loc   Xray  Op 245MHz 10cm   Sweep
None
B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to unsettled throughout the day.
D. Stratwarm
STRATWARM ALERT/TUESDAY/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 20HPA. IN THE MIDDLE AND UPPER STRATOSPHERE THE COLD AND ELONGATED POLAR VORTEX WEAKENS. SLOW TRANSITION TO SUMMER CONDITIONS MOST PROBABLE.
E. Daily Indices: (real-time preliminary/estimated values)
10 cm 147  SSN 110  Afr/Ap 006/007   X-ray Background B5.1
