ACE data indicated solar wind returned to background conditions. Solar
wind speeds exhibited a slow but steady decrease throughout the period,
diminishing from a high of 440 km/s at the beginning of the period down
to a low of 361 km/s by the end of the period. IMF Bt remained
steady in the 1 to 3 nT range, while IMF Bz was variable in the +/- 3 nT
range. IMF Phi data indicated a positive-polarity (Away) orientation for
the majority of the period with only a few oscillations into the
negative sector.
