Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 194 Issued at 0245Z on 13 Jul 2002 This report is compiled from data received at SWO on 12 Jul

B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field activity was at unsettled to minor storm levels. A coronal hole in the southwest quadrant in concert with a weak eastern flanking shock, from the partial halo CME observed on the 7th of July, is believed to be responsible for the elevated geomagnetic field activity.
