Joint USAF/NOAA Solar and Geophysical Activity Summary
SGAS Number 056 Issued at 0245Z on 25 Feb 2002
This report is compiled from data received at SWO on 24 Feb
A. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep
1435 1447 1500 9841 S18W44 C4.4 Sf II
B. Proton Events: None
C. Geomagnetic Activity Summary: The geomagnetic field was mostly
quiet with isolated unsettled periods.
D. Stratwarm: STRATWARM ALERT EXISTS STRATWARM SUNDAY
STILL DISTURBED CIRCULATION AND TEMPERATURE PATTERN THROUGHOUT THE
STRATOSPHERE WITH AN ANTICYCLONE OVER GREENLAND AND A DISPLACED
VORTEX OVER NORTHERN SIBERIA. THE WARM AIR COVERS THE POLAR REGION
AND ASIA. THIS LEADS TO A REVERSED TEMPERATURE GRADIENT BETWEEN 60N
AND THE POLE FROM 10HPA UP TO 2HPA AND MEAN ZONAL EASTERLY WINDS AT
60N FROM 3HPA UP TO 1HPA.
E. Daily Indices: (real-time preliminary/estimated values)
10 cm 193 SSN 191 Afr/Ap 006/004 X-ray Background B7.8
Daily Proton Fluence (flux accumulation over 24 hrs)
GT 1 MeV 1.9e+05 GT 10 MeV 1.2e+04 p/(cm2-ster-day)
(GOES-8 satellite synchronous orbit W75 degrees)
Daily Electron Fluence
GT 2 MeV 4.20e+05 e/(cm2-ster-day)
(GOES-8 satellite synchronous orbit W75 degrees)
3 Hour K-indices:
