In afternoon or during dinner: - Install 26/Ic grating setup - CONFIRM THAT THE GRATING TILT IS SET TO EXACTLY 15.55 - NOTE NOTE NOTE: I have switched to a wider slit than the normal 110.5. The new setting is 124 (which is 2.25 arcsec) - check focus - obtain at least 10 Zero frames - obtain at least 5, preferably 10, flat-field frames (projector or dome) Try to get a few good twilight spectra at the beginning (or end) of the night, but only if it would not interfere with observations of target stars. SPECIAL NOTES: I assume the echelle will be in use until sidereal time 19:00, which will be about 2230 local time. After the switch to the RC spectrograph, please start the program below at whatever stars can be reached when the spectrograph is ready, at an airmass less than 1.6. Probably the first possible target will be SDSS J1529, SDSS J1608, or ASAS 164647. NOTE the new slit setting! PLEASE MAKE A POSITIVE IDENTIFICATION OF EACH STAR USING A LEDAS OR DSS CHART! All coordinates are accurate to better than 1". NOTE: Don't observe any target at airmass > 1.6. Just skip them, since the spectra won't be useful anyway. Make sure to observe as many of the 1+ targets as possible. During the rest of the night, select targets according to the listed priorities. There are more targets than can be observed. Try to take the shorter exposures first where possible, while the moon is still up. Some targets are pretty far north and should be observed as near the meridian as possible.
