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.

C. Geomagnetic Activity Summary
THE GEOMAGNETIC FIELD WAS QUIET TO
ACTIVE. THE MOST DISTURBED PERIOD WAS FROM 09/2100-10/0000Z. DURING
THE PERIOD, SOLAR WIND VELOCITY SLOWLY DECREASED TO NEAR 520 KM/S.
THIS DECREASE WAS NOT OBSERVED FROM THIS CORONAL HOLE LAST SOLAR
ROTATION. ENERGETIC ELECTRON FLUXES AT GEOSYNCHRONOUS ORBIT REACHED
HIGH LEVELS DURING THE PERIOD.
