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 at quiet
to major storm levels. A CME was observed to pass the ACE spacecraft
at around 02/2200Z. Though it was a relatively modest shock, several
extended periods of southward IMF Bz ensued, creating the minor to
major storm periods. The storm is assumed to be associated with the
CME activity observed early on 30 Sep.
