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 ranged from
quiet to severe storm levels. Transient flow, likely the CME
activity from 04 and 05 January, impacted the geomagnetic field
first at around 07/0900Z. The existing elevated solar wind speed
increased from 500 km/s to just over 600 km/s. Major storming
followed a period of sustained southward Bz to near -10 nT between
07/1300 - 1500Z. A second disturbance passed the ACE spacecraft at
07/2010Z. Only a weak enhancement was observed on the plasma
measurements; however, the IMF Bz turned sharply southward to near
-20 nT. The geomagnetic field responded with major to severe storm
conditions to end the period.
