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.

B. Proton Events
None.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
unsettled with an isolated active period between 0300Z to 0600Z.
The active conditions followed a period of southward IMF Bz. Solar
wind plasma and magnetic field measurements indicate the presence of
a weak coronal hole stream.
D. Stratwarm
None.
