In afternoon or during dinner: - Install 13/I grating setup - check focus if necessary If there is time: - obtain at least 25 Zero frames - obtain at least 5, preferably 25, flat-field frames (projector or dome) otherwise, do the Zero and pflat exposures at the end of the night. Then switch to the echelle. The echelle is scheduled every night in August until LST = 19h. Tonight the echelle is scheduled until 2136 local time. At 2136 CST, switch to the RC spectrograph. I assume 30 minutes overhead for the change of instruments.

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, and replace with a repeat observation of 0235+164 C: cataclysmic variable: may be fainter than on finding chart. G: galaxy. Center on nucleus. N: fading nova o: check finding chart. 40 Eri B is the SE component of a triple system. PP: if not done at the start of the night. Be sure to get one set of bias frames either at the start of end of the night. PM: may have appreciable proper motion. -------------------------------------------------------------------- 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 .............................................................................. Notes about finding charts: Charts are at www.astro.yale.edu/buxton/smarts/find_charts/blazars/blazars.html RA & Dec: all coordinates are accurate to 1"; charts can be generated by operator as necessary using LEDAS or DSS. ..............................................................................
