Observations from the ACE spacecraft reflected the waning influence of a
high speed solar wind stream. Speed declined through the period,
beginning near 650 km/s and ending near 450 km/s. Phi remained positive.
Bt was at or below 7 nT and Bz never dipped below -6 nT. Density began
a slow rise after 22/0000 UTC while temperature began to decline.
