The solar wind environment at the ACE spacecraft reflected nominal solar
wind conditions. Wind speed began the period ranging between just above
400 km/s to nearly 460 km/s, but steadily decreased to near 385 km/s
range by the end of the period. IMF Bt remained steady near 4 nT for
most of the period. The Bz component of the IMF remained mostly positive
until just after the new UT day. It then transitioned to mostly
negative, ranging from 0 to -3 nT to end the period. Phi angle remained
in a positive (away) orientation throughout the day.
