Solar wind parameters continued under the influence of a negative
polarity coronal hole high speed stream (CH HSS). Solar wind speeds
ranged from 435 km/s to 631 km/s. Total field was between 2 nT and 7 nT
while the Bz component varied between -6 nT and +4 nT. Phi angle was
predominantly negative (towards) with minor deflections into a positive
(away) sector.
