Solar wind summary

Solar wind speeds continued a somewhat unstable climb throughout the
period in response to the likely delayed onset of anticipated weak
coronal hole high-speed stream (CH HSS). Speeds began the period near
320 km/s, then increased to a peak of just under 400 km/s before
dropping back down to the mid 300s by the end of the UT day. Another
slow rise occurred just after the beginning of the new day with a peak
near 390 km/s then a slow but steady decrease to end the period at
approximately 350 km/s. IMF Bt peaked near 9 nT at the beginning of the
period, but has steadily decreased to around 5 nT. IMF Bz was unstable
as well remaining mostly positive with intermittent decreases to near -5
nT. IMF Phi remained in a primarily negative (toward) orientation for
the majority of the period.
