The solar wind environment at the ACE spacecraft was nominal. Wind
speed remained in the mid 300 km/s range. Bt was less than 6 nT for
most of the period and Bz never dropped below -4 nT. The Phi angle was
mostly negative (toward). A small discontinuity was observed around
25/0350 UTC when wind speed increased from around 320 to 360 km/s and
Phi shifted slightly toward positive.
