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.
