Solar wind parameters, measured at the ACE spacecraft, were indicative
of diminishing CH HSS influence. Solar wind speed generally decreased
from values near 620 km/s to end-of-period values near 435 km/s. The
total field strength ranged from 5 nT to 10 nT while the Bz component
ranged from +6 nT to -9 nT. The phi angle remained oriented in a
positive (away) sector through approximately 11/0200 UTC and has been
variable since that time.
