The solar wind environment at the ACE spacecraft was nominal. Wind
speed remained in the mid 300 km/s range. The interplanetary magnetic
field (IMF) Bt ranged between 2 to 6 nT with the Bz component did not
vary much beyond +/- 4 nT. The phi angle was in a predominately positive
(towards) orientation through the period. A small discontinuity was
observed around 25/0350 UTC when small increases were observed in
temperature, density and wind speed.
