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.

C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
active. Active periods are due to the effects of a recurrent coronal
hole high speed stream. At approximately 28/0330 UTC a Co-rotating
Interaction Region (CIR) was observed at ACE preceding the coronal
hole high speed stream. Solar wind speed at ACE increased from
approximately 275 km/s to 550 km/s and decreased slightly to around
420 km/s.
