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 to unsettled. Solar wind speed remains elevated - near 550
km/s, due to a high speed coronal hole stream. The high speed
stream is declining as the coronal hole rotates out of a
geoeffective position. The greater than 2 MeV electron fluxes at
geosynchronous orbit once again reached high levels.
D. Stratwarm
STRATWARM ALERT / SUNDAY / STRATWARM EXISTS
INTENSE WARMING COMTINUES IN THE UPPER STRATOSPHERE. WITHIN THE NEXT
THREE DAYS: EASILY WINDS AT 60N IN 1 HPA; REVERSED TEMPERATURE
GRADIENT BETWEEN THE NORTH POLE AND 60N FROM 10 TO 1 HPA; AN
ELONGATION OF THE COLD POLAR VORTEX INTO TWO CENTRES IN THE LOWER
AND MID-STRATOSPHERE.
