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
The greater than 10 MeV proton flux decreased
below S1 (Minor) levels early in the period. The peak flux was 30
pfu at 24/0025 UTC.
C. Geomagnetic Activity Summary
Geomagnetic field activity began
the period at active conditions due to waning conditions from the 21
Jun CME. The geomagnetic field activity decreased to unsettled and
eventually to quiet conditions as a result of weak field strength
and weak negative Bz.
