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 100 MeV proton event that began at 04/1650 UTC ended at 06/2315 UTC. The maximum flux for this event was 253 PFU at 06/0220 UTC. The greater than 10 MeV event that began at 04/1705 UTC continued. The maximum flux for this event was 31,700 PFU at 06/0215 UTC. The greater than 10 MeV flux was 137 PFU at the close of the period and was gradually decreasing.
C. Geomagnetic Activity Summary
Activity was at active to minor storm levels until 07/0600 UTC, then decreased to mostly quiet to unsettled levels for the remainder of the period.
