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 Sunday
Lower stratosphere circulation remains disturbed as
a result of the major warming. Reversed temperature
gradient up to 20 hpa. The vortex is weakening and
becoming less disturbed. Slow transition to summer
conditions most probable.
