(* means a trouble report has been issued or appended to)
The telescope was opened at 21:20.  Mike Ledlow and Mark Bliton were on site
for the NM07 run.  Mike chose to use GRIM2 for the entire evening.
He was obtaining data for a feasibility study using GRIM in Spectral mode,
taking IR spectra for galaxies that already have a published IR spectra.
He will compare both to clarify the usefulness of proposing in the fourth
quarter to observe new targets.
The sky was plagued with cirrus and haze for a large part of the evening.
