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.
