In afternoon or during dinner: - Install 9/Ib grating setup - check focus if necessary If there is time: - obtain at least 25 Zero frames - obtain at least 10, 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 NOAO 08b-02 program is scheduled until 2116 local time. At 2116 local time switch to the RC spectrograph. I assume 30 minutes overhead for the change of instruments. Verify the 9/Ib setup. ---------------------------------------------------------------------------- Program Pri Target RA (J2000) Dec mag Exp Cmp T CST Rem NO 07A-0499 1 [041] 15 57 16.51 -62 16 24.3 15.8 1x 900 1 23 21 46 NO 07A-0499 1 [058] 16 49 02.39 -36 42 57.0 16.5 1x1200 1 28 22 9 NO 07A-0499 1 [082] 17 17 22.14 -26 50 06.8 17.3 3x1200 1 70 22 37 NO 07A-0499 2 [495] 17 35 30.21 -47 14 41.9 15.6 1x 720 1 20 23 47 NO 07A-0499 3 [937] 19 46 41.85 -25 14 02.3 15.3 1x 540 1 17 0 7 NO 07A-0499 3 [938] 19 50 33.56 -25 55 11.1 15.3 1x 720 1 20 0 24 NO 07A-0499 3 [940] 19 53 17.21 -27 02 13.2 15.2 1x 300 1 13 0 44 NO 07A-0499 3 [941] 19 56 29.91 -25 22 02.8 15.1 1x 300 1 13 0 57 NO 07A-0499 3 [953] 20 48 30.05 -39 23 56.4 15.0 1x 600 1 18 1 10 NO 07A-0499 3 [959] 21 00 34.24 -39 53 12.1 15.1 1x 780 1 21 1 28 NO 07A-0499 3 [960] 21 01 42.61 -28 07 21.3 15.3 1x 720 1 20 1 49 NO 07A-0499 3 [971] 21 43 02.10 -72 39 34.9 15.1 1x 480 1 16 2 9 NO 07A-0499 3 [975] 21 52 39.29 -84 55 24.7 15.4 1x 840 1 22 2 25 NO 07A-0499 3 [977] 21 54 57.01 -68 22 46.7 15.0 1x 420 1 15 2 47 NO 07A-0499 3 [985] 22 35 11.01 -52 23 23.9 14.9 1x 360 1 14 3 2 NO 07A-0499 3 [987] 22 47 05.96 -77 42 21.3 15.5 1x 780 1 21 3 16 NO 07A-0499 3 [990] 23 05 57.46 -78 26 29.6 15.5 1x1080 1 26 3 37 NO 07A-0499 3 [991] 23 15 17.35 -67 13 26.9 15.1 1x 660 1 19 4 3 NO 07A-0499 3 [992] 23 27 46.12 -47 45 41.5 14.9 1x 480 1 16 4 22 NO 07A-0499 3 [993] 23 28 55.71 -52 12 34.1 15.0 1x 420 1 15 4 38 NO 07A-0499 3 [562] 0 03 57.76 -44 31 49.9 15.0 1x 600 1 18 4 53 NO 07A-0499 1 [999] 3 22 41.70 -37 12 30.0 9.9 1x 360 1 14 5 11 SUNY 08B-02 + V1647 Ori 5 46 13.14 -00 06 04.8 16.7 3x 900 1 54 5 25 RV cal 1 pflat --- --- 0 10 6 19 PP end 9/Ib 6 29 If there is any time left before dawn, or you get ahead and have to wait for targets to rise, or if some targets are too faint to acquire, please select from among the following 9/Ib targets: NO 07A-0499 2 [473] 16 49 03.31 -52 43 13.7 15.9 2x 780 1 35 21 44 NO 07A-0499 2 [479] 16 52 49.18 -28 36 43.2 15.4 1x 780 1 21 22 18 NO 07A-0499 3 [563] 0 17 49.06 -48 29 59.0 14.8 1x 360 1 14 5 3 NO 07A-0499 3 [567] 0 58 30.65 -53 37 11.7 15.0 1x 360 1 14 5 17 NO 07A-0499 3 [568] 1 02 57.20 -60 53 38.7 14.9 1x 420 1 15 5 30 Just before sunrise, get well-exposed TWILIGHT SPECTRA at zenith.

Be sure to get one set of bias frames either at the start of end of the night. RV: radial velocity standard. ..............................................................................
