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.

None
C. Geomagnetic Activity Summary
THE GEOMAGNETIC FIELD RANGED FROM
QUIET TO MAJOR STORM LEVELS. THE DAY BEGAN WITH QUIET TO UNSETTLED
CONDITIONS. A SINGLE PERIOD OF MAJOR STORMING WAS OBSERVED AT
BOULDER DURING 05/0600-0900Z, WITH MORE EXTENSIVE MINOR STORMING
OBSERVED AT HIGHER LATITUDES DURING 05/0600-1200Z. THE REMAINDER OF
THE DAY SAW UNSETTLED TO ACTIVE CONDITIONS. THE ENHANCED ACTIVITY
IS ATTRIBUTED TO INCREASING SOLAR WIND SPEEDS, WHICH BEGAN RISING
AROUND 05/0800Z FROM 450 KM/S TO NEAR 600 KM/S BY 05/1000Z, AND
SUBSEQUENT SUSTAINED PERIODS OF NEGATIVE BZ NEAR -10 NT.
