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.

  Planetary K indices from 1800-2400Z are not available
due to network issues, NOAA Kp estimates were used during those
times.  The daily Ap is estimated.
