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
None.
C. Geomagnetic Activity Summary
The geomagnetic field reached
major storm levels during the first two synoptic periods, before
decreasing to minor storm levels during the third synoptic period.
These storming levels were in response to CME effects. Afterwards,
the geomagnetic response was at quiet to active levels as CME
effects waned.
