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
Geomagnetic field activity was at quiet levels throughout the day.
D. Stratwarm
stratwarm alert exists stratwarm thursday as a result of the major warming, the circulation on 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 transition to summer conditions most probable.
