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 at quiet
to minor storm levels. Active to minor storm periods were observed
from 19/0300-0900 UTC due to a prolonged period of southward Bz in
conjunction with a solar sector boundary crossing.
