Solar wind parameters were at background levels for most of the period.
Solar wind speed, as measured by the ACE spacecraft, began the period
near 410 km/s, reached a peak speed of 420 km/s at 10/0804 UTC, and
ended the period near 360 km/s. Total IMF started and ended the period
near 3 nT, varying slightly between 0 nT and 4 nT throughout the
period. Bz fluctuated between +/-3 nT throughout the period. The phi
angle remained in a predominantly positive (away) orientation for most
of the period, but exhibited signs of negative (towards) oscillations
intermittently through the period.
