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.

None.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
unsettled with an active period on 25 October between 0900 and 1200
UTC. The active period was most likely due to a geoeffective
coronal hole. ACE data show solar wind speed has remained around
500 km/s, however the total interplanetary magnetic field strength
has decreased from approximately 10 nT to 4 nT.
D. Stratwarm
None.
