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 Advanced Composition Explorer (ACE)
satellite hinted that a weak shock passage occurred at approximately
30/0030 UTC, with unsettled conditions following. This was believed
to be from the disappearing filament from 27 May.
