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.

Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 347 Issued at 0245Z on 12 Dec 2000 This report is compiled from data received at SWO on 11 Dec

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.
