Solar wind parameters, as measured by the ACE spacecraft, continued to
reflect background conditions. Wind speeds ranged between 250 and 335
km/s. Total IMF (Bt) was steady between +4 to +6 nT during the first
half of the period but showed a slight increase at approximately 12/2000
UTC to +9 nT. The Bz component of the IMF reached a maximum southward
extent of -8 nT at 12/2029 UTC. The phi angle was oriented in a negative
(toward) solar sector during the period.
