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 at quiet
to minor storm levels with a period of major storm conditions
between 16/0300 UTC and 0600 UTC. Solar wind speed at ACE has been
steadily decreasing from approximately 700 km/s to 550 km/s until
16/2240 UTC when the speed increased to 600 km/s. The Bz component
of the IMF has remained south between -1 nT and -10 nT during this
reporting period. The greater than 2 MeV electron flux at
geosynchronous orbit was high today.
