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
unsettled.
D. Stratwarm
Stratwarm alert exists stratwarm Saturday
The circulation in the lower stratosphere remains
disturbed as a result of the major warming. The
reversed temperature gradient persists up to 20 hpa.
In the middle and upper stratosphere, the vortex
weakens and becomes less distorted. Slow transition
to summer conditions most probable.
