Solar wind parameters, measured at ACE, were indicative of waning
coronal hole high speed stream (CH HSS) influence. Solar wind speed
varied between 360 km/s and 480 km/s to begin the period, but eventually
settle down to consistently average near 380 km/s. Total field was
fairly steady between 6 nT to 7 nT, while the Bz component was mostly
negative, ranging between +4 nT and -7 nT. Phi angle remained mostly
positive (away) throughout the period.
