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.

None
C. Geomagnetic Activity Summary
The geomagnetic field was at
unsettled to minor storm levels. The transequatorial coronal hole
in the western solar hemisphere continues to elevate the solar wind
(today's approximate average speed of 625 km/s). The greater than 2
MeV electron flux at geosychronous orbit reached high levels today.
