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 activity was
at quiet to active levels. An isolated minor storm condition was
observed at Fredericksburg at 06/2100 UTC, believed to be a result
of a large, transequatorial coronal hole during it's waning stage.
The greater than 2 MeV electron flux at geosynchronous orbit has
been elevated throughout the period following the passage of the
high speed stream.
D. Stratwarm
STRATWARM ALERT EXISTS STRATWARM THURSDAY
IN THE MIDDLE AND UPPER STRATOSPHERE, STILL DISTURBED CONDITIONS
AFTER THE WARMING. STILL A REVERSED TEMPERATURE GRADIENT AT 10HPA,
BUT FURTHER RETURNING TO NORMAL CONDITIONS. END OF THIS ALERT
PERIOD.
