In afternoon or during dinner: - Install 47/II grating setup - obtain at least 10 Zero frames - obtain at least 5, preferably 10, flat-field frames (projector or dome) Get well-exposed TWILIGHT SPECTRA at zenith at beginning of night. Aim for 3 spectra, each with between 5,000 and 30,000 counts per pixel. Start with the following list of targets and observe as many of them as possible until the airmass reaches about 2.8 (or whatever you believe is a safe airmass, less than 2.8 if necessary). If any targets are found to be close pairs, try to get separate spectra of both of them if possible.

General Notes: Pri: Target priority. 1 = observe object if possible 2 = extra targets; observe only if no Priority 1 target is available 3 = backup targets; low priority RA & Dec: all coordinates are accurate to 1"; charts can be generated by operator as necessary using LEDAS or DSS. Charts for many objects were prepared at telescope in February and should be available. Cmp: 1 means take comparison spectrum only before target exposures; 2 means before and after ..............................................................................
