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 throughout the day. A single unsettled period
was observed at Boulder during 1500-1800 UTC. The greater-than-2
MeV electron flux at geosynchronous orbit was elevated at moderate
levels (above 1000 pfu) during local daytime hours.
D. Stratwarm
STRATWARM ALERT/TUESDAY/STRATWARM EXISTS.
MAJOR WARMING CONTINUES. 5 AND 8-DAY FORECASTS
INDICATE A VORTEX SPLITTING EVENT TO FORM TWO NEW
CENTRES OVER THE CANADIAN ARCTIC AND A WEAKER
CENTRE OVER SIBERIA. THE WARM AIR OVER SIBERIA AND
RUSSIA COOLS SLIGHTLY AND SPREADS TO THE WEST.
