APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday May 25, 2008 (MJD 54612) ---=== OBSERVING TEAM ===--- Shannon Watters Howard Brewington Audrey Simmons (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The black cloth that covers the laptop at the 2.5-meter has a large hole and needs to be replaced. Finished plates: 2922, 2175 Added signal to plates: 2928, 2724, 2180 We checked the neon lamps during all cals, and they worked. ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems during checkout. Spectro collimation set for ~10C tonight. Mounted cart 1, plate 2922. Started ventilating at 01:17Z with the doors and louvers open, fans on. Night: ------ 02:01Z Sunset 02:02Z Enclosure off, topped-off spectro secondary dewars, checked top/bottom balance, did a test slew, checked fiducial crossings for each axis, started the DIMM. 02:30Z Cart 01, plate 2922 (segFaint180).
