In afternoon or during dinner: - Install 32/I grating setup - check focus if necessary - obtain at least 25 Zero frames - obtain at least 5, preferably 25, flat-field frames (projector or dome) Get well-exposed TWILIGHT SPECTRA at zenith at beginning of night. Aim for three spectra, each with between 5,000 and 30,000 counts per pixel.

Aim for 3-5 spectra, each with between 5,000 and 30,000 counts per pixel. -------------------------------------------------------------------- Remarks: M: moon within 10 deg. Skip if you do not see the star in the acquisition TV C: cataclysmic variable: may be fainter than on finding chart. If any emission lines are overexposed in the first spectrum, shorten the exposure time and take 3 more. F: Faint supernova may be difficult to see with moon up. G: galaxy. Center on nucleus. N: fading nova PM: may have significant proper motion. S: same as previous target; different exposure time. Do not move telescope. -------------------------------------------------------------------- General Notes: Astronomical ephemerides are from SKYCAL,by John Thorstensen Pri: Target priority. 1 = observe object if possible 2 = extra targets; observe only if no Priority 1 target is available 3 = backup/filler targets; low priority Cmp: 1 means take comparison spectrum only before target exposures; 2 means before and after The T column lists the approximate time in minutes for this line. This includes 5 minutes acquisition plus 1 minute for the comparison. The CDT column is the approximate local start time assumed for scheduling purposes. If you fall too far behind, you may need to drop some priority 2 or 3 targets, but otherwise don't pay too much attention to it. For now I am allotting the nominal overheads, plus 20-25 minutes for changes in the grating tilt/filter. .............................................................................. Notes about finding charts: RA & Dec: all coordinates are accurate to 1"; charts can be generated by operator as necessary using LEDAS or DSS. Charts for most targets are on-line through the link at the top of the 1.5m scheduling page. Many charts may also available at the telescope.
