Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 198 Issued at 0245Z on 17 Jul 2005 This report is compiled from data received at SWO on 16 Jul

B. Proton Events
The greater than 10 MeV proton event that began on 14/0245Z, had a peak flux of 134 pfu at 15/0345Z, remains in-progress. The proton flux has been on a gradual decrease and was near 10 pfu at the end of the period.
C. Geomagnetic Activity Summary
The geomagnetic field was at predominantly quiet to unsettled levels. An active period occurred at the Boulder magnetometer between 16/0600 and 0900Z. A weak transient signature was observed at the ACE spacecraft near 16/0100Z with no significant geomagnetic effects resulting.
