Solar wind parameters, as measured by the ACE spacecraft, reflected
predominately nominal conditions for the period. Wind speed values
averaged near 340 km/s. Total field values rose to near 10 nT multiple
times, but intermittently. The Bz component decreased to near -5 nT for
an extended period between 21/0100 and 21/0900 UTC. The phi angle was in
a predominately negative (toward) orientation.
