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.

B. Proton Events
None
C. Geomagnetic Activity Summary
Quiet to unsettled.
D. Stratwarm
Stratwarm alert exists Saturday.
As a result of the major warming, the circulation in the lower and
middle stratosphere remains disturbed. Still, a reversed temperature
gradient remains between 60N and the pole in the lower and middle
stratosphere.
