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.

F. Comments
  A shock passed the ACE spacecraft at 12/1050 UTC and
created a sudden impulse at Earth of 23 nt at 12/1136 UTC.  Solar
wind velocity increased from 336 km/s to 406 km/s and density jumped
from 6 p/cc to 35 p/cc.
