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 146 Issued at 0245Z on 26 May 2003 This report is compiled from data received at SWO on 25 MayA. Energetic Events

B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet
to minor storm levels. An oscillating Bz component of the
interplanetary magnetic field allowed for two consecutive periods of
minor storm conditions at both the middle and high latitudes during
local nighttime hours. Elevated conditions are due to a high speed
stream coronal hole. The greater than 2 MeV electron fluxes at
geosynchronous orbit reached high levels today.
