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. Coronal hole high speed stream flow is declining, following peak speeds that exceeded 600 km/s. The sustained southward IMF Bz that persisted for the past few days also appears to have ended. The greater than 2 MeV electrons at geosynchronous orbit have again reached high levels.
