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/wednesday/stratwarm exists.
as a result of the major warming the circulation
in the lower stratosphere remains further disturbed
leading to a reversed temperature gradient up to
20 hpa.
in the middle and upper stratosphere the cold and
elongated vortex weakens.
slow transitions to summer conditions most probable.
