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 242 Issued at 0245Z on 29 Aug 2004 This report is compiled from data received at SWO on 28 Aug
A. Energetic Events
Begin  Max  End  Rgn   Loc   Xray  Op 245MHz 10cm   Sweep

B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was at predominantly quiet to unsettled levels. There was an isolated active period that occurred between 28/0600 and 0900Z in response to southward Bz oscillations in the interplanetary magnetic field.
D. Stratwarm
None

F. Comments
  The ACE spacecraft orbit will 
bring ACE to its closest approach with the Sun 
on August 30, 2004. During that time possible 
solar radio noise may interfere with spacecraft 
telemetry resulting in the loss of real time 
solar wind plasma, magnetic field, and particle 
data.
