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 active levels. The effects from a geo-effective coronal hole
continued today and produced an isolated active condition early in
the period. Solar wind velocity increased to near 800 km/s around
24/1400 UTC. The greater than 2 MeV electron flux at
geo-synchronous orbit exceeded event threshold today.
D. Stratwarm

60N AND THE POLE AT 5 HPA.
