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 was at minor storm levels to begin the period from 30/0000-0600Z due to residual coronal hole high speed stream effects. Quiet conditions prevailed for the remainder of the day.
