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 minor storm levels. A slight indication of a weak shock passage at the ACE spacecraft was observed at the beginning of the period. The greater than 2 MeV electron flux at geo-synchronous orbit exceeded threshold at 16/1505 UTC, preliminary maximum flux was 1340 pfu at 16/1530 UTC.
