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.

B. Proton Events
THE GT 10 MEV LEVELS ROSE ABOVE THE 10 PFU
THRESHOLD FOR 25 MINUTES STARTING AT 08/0245UT. LEVELS DECLINED TO
LOW LEVELS OVER THE REMAINDER OF THE PERIOD.
C. Geomagnetic Activity Summary
THE GEOMAGNETIC FIELD WAS QUIET TO
SEVERE STORM. THE CME REPORTED ON 5 NOV ARRIVED AT AND INTERACTED
WITH THE EARTH'S MAGNETOSPHERE, CAUSING SEVERE STORM CONDITIONS
DURING THE 06-09UT PERIOD. THE GT 10 MEV PROTONS CLIMBED PAST THE
10 PFU THRESHOLD FOR APPROXIMATELY 25 MINUTES STARTING AT 08/0245UT.
THEY HAVE DECLINED TO LOW LEVELS SINCE THAT TIME.
D. Stratwarm
None.
