ACE data indicated slightly enhanced solar wind conditions at the
beginning of the period, with the IMF total field reaching 11 nT and a
maximum Bz deflection of -10 nT. This enhancement was likely associated
with a solar sector boundary crossing that occurred earlier in the
period, with the effects being short-lived. Nominal conditions returned
after 26/1600 UTC and have lasted throughout the rest of the period. The
coronal hole high-speed stream (CH HSS) that was expected to commence
today has yet to materialize. Wind speed ranged from 255 to 296 km/s at
the beginning of the period before decreasing and stabilizing to near
270 km/s at the end of the period.
