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. At 04/1335 UTC, the greater than 2 MeV electron flux
exceeded event threshold at GOES-8 in geosynchronous orbit (75W).
Flux levels remained above 1000 pfu for about nine hours, reaching a
max of about 1960 pfu near local noon.
