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 reached minor storm conditions during the 24/0300 and 24/0600 UTC synoptic periods in response to the high speed solar wind stream. The remainder of the period saw a wane from active to quiet conditions.
