Joint USAF/NOAA Solar and Geophysical Activity Summary
SGAS Number 053 Issued at 0245Z on 22 Feb 2002
This report is compiled from data received at SWO on 21 Feb

B. Proton Events: The greater than 10 MeV protons at geosynchronous
orbit remain elevated following the small proton event that began
and ended between 20/0730 - 0800Z.
C. Geomagnetic Activity Summary: The geomagnetic field was quiet to
unsettled.
