Geophysical report

Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 215 Issued at 0245Z on 02 Aug 2004 This report is compiled from data received at SWO on 01 Aug

B. Proton Events

C. Geomagnetic Activity Summary
The geomagnetic field ranged from quiet to active levels. A shock passage was observed by the ACE spacecraft at approximately 01/0130Z. This transient is believed to be the result of the long duration C2 x-ray flare that peaked at 29/1304Z from old Region 652 (N08, L=348) while it was exiting the west limb. The Bz component of the interplanetary magnetic field went south for a brief period of time allowing for observed active periods between 01/0130 and 0300Z.
