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 ranged from
quiet to active levels. Solar wind speeds increased up to around 600
km/s at 02/2300 UTC, but dropped down to 500-550 km/s from 0100-1900
UTC. However, there appears to be another solar wind speed increase
in progress at this time. The greater than 2 MeV fluence at
geosynchronous orbit reached moderate levels today.
