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 ranged from
quiet to major storm levels. ACE data indicates that a shock passed
the instrument at approximately 16/2100Z. This transient is
believed to have been the result of the full halo CME activity seen
on 13 July.
