5 December


Solar wind parameters, as measured by the ACE spacecraft, remained at
background conditions throughout the period. Solar wind speed reached an
isolated peak of 422 km/s at 04/1350 UTC, but remained in the mid 300
km/s range for most of the period. Total IMF steadily fluctuated between
4 nT and 6 nT with isolated dips to near 2 nT. IMF Bz remained negative
for most of the period with isolated northward transitions to near 1 nT
and 3 nT. Phi angle remained in a predominately positive (away)
orientation throughout the period.
