Solar wind speeds remained stable just under 300 km/s for the first half
of the period, then began a slow but steady increase to just under 340
km/s near the end of the period in response to the likely arrival of the
anticipated weak coronal hole high speed stream (CH HSS). IMF Bt began
the period near 3 nT, then increased slightly to 5 nT and ended the
period near 7 nT. IMF Bz was weakly positive for most of the period with
isolated decreases to approximately -5 nT. Phi remained in a primarily
negative (toward) orientation for the majority of the period.
