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 was quiet to
active. Mostly unsettled conditions prevailed early in the period in
response to a waning high speed coronal hole stream. Solar wind data
indicated another high speed stream onset at around 1300Z, preceded
by a weak co-rotating interaction region. Solar wind speed ranged
from 500 - 550 km/s for the latter half of the period and isolated
active periods were observed at all latitudes. The greater than 2
MeV electron flux at geosynchronous orbit reached high levels.
