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 a single period of unsettled conditions observed during the interval 21/0900-1200Z.
D. Stratwarm
STRATWARM ALERT EXISTS STRATWARM THURSDAY STRONG STRATOSPHERIC MINOR WARMING CONTINUES. A SPLIT VORTEX IN THE LOWER STRATOSPHERE EXISTS WITH THE MAIN CENTER OVER CANADA AND A MINOR CENTER WEST OF THE BAIKAL SEA WEAKENING. A WARM ANTICYCLONE IS LOCATED OVER THE NORWEGEAN SEA WITH THE WARM AIR OVER THE BARENTS SEA. AT 5 AND 10 HPA A REVERSED TEMPERATURE GRADIENT EXISTS BETWEEN 60N AND THE POLE. MEAN ZONAL WIND IS VERY WEAK FROM THE WEST IN THE UPPER STRATOSPHERE.
