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 initially at unsettled levels but has been at active to minor storm levels since 08/0000 UTC and continuing through the end of the reporting period (08/2100 UTC). The geomagnetic field continues to be buffeted by a persistent high speed solar wind stream with velocities in the 700 to 800 km/s range and Bz values varying between -8 nT to +1 nT. The greater than 2 MeV electron fluxes continue to be at high levels.
