General notes: 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 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 30 minutes for a change in the grating tilt/filter. .............................................................................. In afternoon or during dinner: - Install 26/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 degrees. Skip if you do not see the star in the acquisition TV M*: moon within 5 degrees. Skip if you do not see the star in the acquisition TV C: cataclysmic variable. May be fainter than in finding chart. Skip if not visible. If visible but much fainter than on chart, increase exposure times to 3x600. F: faint target may be hard to see with full moon up. N3: formerly known as Nova Sag 2004 R: radial velocity standard for STSI programs. X: new nova (IAU Circular 8323) Check the first exposure to make sure there is no part that is saturated (this is possible if there are very strong emission lines); if so, reduce the exposure and take 3 good ones. If the first spectrum is very underexposed, increase the exposure accordingly. 3: 5 arcsec SE of brighter star. PM: may have significant proper motion. -------------------------------------------------------------------- General Notes: Astronomical ephemerides are from SKYCAL,by John Thorstensen Pri: Target priority. + = observe at all costs! 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 .............................................................................. 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 many objects should be available at the telescope.
