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 119 Issued at 0245Z on 29 Apr 2003 This report is compiled from data received at SWO on 28 Apr

None
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet to minor storm levels. A very weak signature from the NASA/ACE data indicate a transient may have passed around 28/1200Z although the elevated geomagnetic conditions are believed to be from a recurrent coronal hole. The greater than 2 MeV electron fluxes at geosynchronous orbit have again reached high levels.
