Solar wind parameters observed at ACE displayed slightly elevated
conditions with solar wind speeds averaging 470 km/s, increased over
from near 400 km/s over the past 24 hours. Associated with elevated
speeds was an increase in Bt with average potential near 8 nT. Bz was
mostly positive, but a period near -5 nt was observed over the past few
hours. Phi angle was steady at a positive (away) orientation. These
conditions are believed to be the result of a high speed stream from CH
76, a positive polarity feature.
