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 minor storm levels. The Bz component of the interplanetary
magnetic field ranged from +/- 10 nT throughout the period due to a
recurrent high speed stream (approximately 525 km/s at the time of
this writing). The greater than 2 MeV electron fluxes at
geosynchronous orbit reached moderate levels today.
