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
predominantly quiet, with one unsettled period observed early in the
day (00-03 UTC). The greater-than-2 MeV electron flux at
geosynchronous orbit was above threshold, reaching moderate levels
(exceeding 1000 pfu) during local daytime hours.
D. Stratwarm
STRATWARM ALERT/MONDAY/STRATWARM EXISTS.
MAJOR WARMING IN PROGRESS. THE VORTEX CENTER, CURRENTLY NORTH OF
GREENLAND, SPLITS INTO TWO NEW CENTERS OVER CENTRAL RUSSIA AND
HUDSON BAY WITH AN ANTICYCLONE MOVING OVER THE POLE AND COLD AIR
DEVELOPING OVER THE CANADIAN ARCTIC AND WESTERN SIBERIA.
