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. The ACE satellite indicated the passage of a
weak shock (presumed to be the result of the M1 flare at 07/0346
UTC) at approximately 09/0900 UTC. The Bz energy channel remained
north and several periods of unsettled conditions persisted.
