In afternoon or during dinner: - Install 9/Ic grating setup - check focus if necessary - obtain at least 25 Zero frames - obtain at least 10, 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. Remember to take a comp spectrum too.

Aim for 3-5 spectra, each with between 5,000 and 30,000 counts per pixel. Remember to take a comp spectrum too. -------------------------------------------------------------------- Remarks: A: star 142 lies south of a slightly fainter star B: star 3 is not marked on the finding chart, but is the bright star directly north of star 147 (27 arcsec N of star 147). C: star 204 is a faint star lying to the west of a much brighter star. It can only be observed if instrument is rotated 90 degrees to get the bright star off the slit. A 20 minute allowance is included for each rotation.Please reurn to the original orientation after the observation. D: there is a slightly fainter star about 12" to the ENE M: moon within 10 degrees. Skip if not visible in the acquisition TV E: target far to the east. If running ahead, give extra time to the previous target, or observe a backup target if time permits. F: finding chart under SUNY 07A-04 charts . i: I magnitude; V is about 20. N: Nova. Will be fainter than on finding chart. R: radial velocity standard. S2: set slit width to 2.0 arcsec. Be sure to center on the nucleus of the S3: set slit width to 165 (3.0 arcsec). S10: set slit width to 10.0 arcsec. Please reset at the end of the observation. No wavecal is necessary with this exposure. T: monitoring target. Try to maintain spacing between observations. PM: may have significant proper motion. W: star very close to 2 air masses at end of observation. Don't start late; do the calibration lamp at the end if it helps. X: F42-591 is an E-W pair. If you can get them both in the slit, please do so, and replace the second observation with a backup target. Y: 5 arcsec SE of brighter star. Try to keep the brighter star out of the slit. Skip if the seeing is really bad. -------------------------------------------------------------------- General Notes: Astronomical ephemerides are from SKYCAL,by John Thorstensen Pri: Target priority. + = absolute highest 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: RA & Dec: all coordinates are accurate to 1"; charts can be generated by operator as necessary using LEDAS or DSS. Many charts are available via the link from the main 1.5m scheduling page. Charts for many objects should be available at the telescope. ..............................................................................
