Solar wind and interplanetary magnetic field (IMF) parameters, as
measured by the ACE spacecraft, reflected the continued influence of a
positive polarity coronal hole high speed stream (CH HSS). Solar wind
velocity remained elevated through the period, with speeds ranging from
about 550 – 750 km/s. Total magnetic field strength continued to decline
from a high of 7 nT, down to about 3 to 5 nT. The phi angle was
predominantly positive (away) with a few short-spanned oscillations into
the negative (towards) sector.
