Solar wind speed was in decline as coronal hole high speed stream
effects diminished. Solar wind speed reached 478 km/s early in the
period and had decreased to end of period values near 390 km/s. Total
field was fairly steady ranging from 1 nT to 3 nT with the Bz component
variable between +/-3 nT. Phi angle was mostly negative (towards) with
minor deviations into a positive (away) sector.
