(* means a trouble report has been issued or appended to)
Observing specialist: R. McMillan, L. Wells
A good night with excellent seeing.  First half was mostly clear, with
light high clouds appearing during second half.  The humidity was
considerably lower than recent nights.  The pointing (and therefore,
evidently, the tertiary tip/tilt) was fine at the echelle port.
Because of the fine weather, the first half time planned for EN04 was
instead used to obtain the Shack-Hartmann data that is needed before
the new secondary mirror is installed.
