Solar wind parameters, measured at ACE, were indicative of background
conditions. Solar wind speed was relatively steady in the 340 – 410 km/s
range. The total field strength ranged from 10 nT to 1 nT and the Bz
component ranged from +6 nT to -5 nT. The phi angle began the period in
a positive (away) sector and transitioned to a predominantly negative
(toward) sector after 07/1320 UTC. Phi stayed negative, with some minor
variability, through the end of the period.
