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 at GOES was enhanced over the period due to flare and CME activity earlier in the week, but below S1 (Minor) levels. Following the M7 flare, the proton flux began to slowly increase but finished the period just below S1 levels with a peak flux of 8 pfu at 2325Z UTC.
C. Geomagnetic Activity Summary
Geomagnetic field activity began the period at quiet conditions under waning effects from the 22 Jun CME shock. The arrival of the CME driver around 0800 UTC resulted in a geomagnetic response to the G2 (Moderate) level, with subsequent storming at the G1 (Minor) level. The period ended with active conditions.
