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 026 Issued at 0245Z on 26 Jan 2003 This report is compiled from data received at SWO on 25 JanA. Energetic Events

None
C. Geomagnetic Activity Summary
The geomagnetic field has been at
unsettled to minor storm levels. Minor storm levels were reached
due to an elevated solar wind speed near 800 km/s combined with a
seven hour period of negative Bz. Solar wind speed was in gradual
decay at the end of the period.
