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 mostly quiet with one isolated unsettled period in the higher latitudes from 16/1500 - 1800Z. The greater than 2 MeV electron fluxes at geosynchronous orbit attained high levels today.
D. Stratwarm
STRATWARM ALERT EXISTS STRATWARM SATURDAY STRONG STRATOSPHERIC WARMING IN PROGRESS. A SPLIT VORTEX WITH A MAJOR CENTER OVER CANADA AND A SECONDARY CENTER OVER RUSSIA; AN ANTICYCLONE OVER THE PACIFIC AND AN EVOLVING ANTICYCLONE OVER THE NORTH ATLANTIC. COLD AIR CENTERED OVER NORTHERN CANADA; A WARM REGION OVER CENTRAL ASIA, WEAKENING; A NEW WEAK COLD CENTER OVER NORTH EASTERN EUROPE; A WARM REGION DEVELOPING OVER EASTERN CANADA TOWARDS THE NORTH ATLANTIC.
