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 at unsettled to active levels. Elevated solar wind speed near 500 km/s resulted in a disturbed geomagnetic field. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels.
