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 unsettled levels with an isolated active period at middle and
high latitudes between 22/1800 and 2100 UTC. The NASA/ACE
instrument detected a weak shock passage at approximately 22/1300
UTC. The Bz component of the interplanetary magnetic field has been
predominantly north since transient onset. The greater than 2 MeV
electron flux at geosynchronous orbit reached moderate levels today.
