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 has been at
active to minor storm levels with a single period of major storming
at 0600 UTC. The interplanetary magnetic field continues to be
oriented southward, and the solar wind speeds continue to be
elevated well above 450 km/s. During the storm period, wind speeds
were near 650 km/s. There is some evidence in the energetic protons
measured at the L1 orbit that a small interplanetary shock passed
at or near the major storming period.
