Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 168 Issued at 0245Z on 17 Jun 2005 This report is compiled from data received at SWO on 16 Jun
A. Energetic Events

 2001 2022 2042  0775 N09W87 M4.0  Sf        170    II/IV           
B. Proton Events
A greater than 100 and greater than 10 MeV proton event began at 16/2125 and 16/2200 UTC respectively. The greater than 100 MeV peak flux so far is 2.9 pfu; the greater than 10 MeV peak flux so far is 34 pfu. The event was still in progress at time of issue.
C. Geomagnetic Activity Summary
The geomagnetic field ranged from quiet to major storm levels. Transient material associated with the CME activity on 14 June impacted the ACE spacecraft at approximately 16/0830 UTC. A short-lived period of southward IMF Bz to near -16 nT resulted in a major storm from 0900 to 1200 UTC. The period ended with unsettled to active levels.
