APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday October 18, 2007 (MJD 54392) ---=== OBSERVING TEAM ===--- Audrey Simmons (swing) Steph Snedden Shannon Watters ---=== OBSERVING PLAN ===--- SEGUE & SN Science! ---=== OBSERVING SUMMARY ===--- It was photometric all night but the seeing was anywhere from 1.5" to 3". We acquired partial signal on 1 seguefaint plate. We Imaged SNe strip 82 S from lambda=113 to -169 and strip 82 N from lambda=-168.50 to -123 (all including ramps). The DIMM software crashed shortly after 0500Z and we weren't able to recover it (see problems). I opened the pressure building valve on the spectro dewar during the initial night's fill but neglected to close it so we lost about 40 lb of LN2. ---=== OBSERVING LOG ===--- Afternoon: ---------- Set the spectrographs for 5.5C. 23:34Z - Started ventilation. Night: ------ 00:51Z Cart 2, plate 2821, seguefaint167 NGSOGTF (still twilight), FK5 used. T=7.5 C, relfoc=-130, seeing~1.3" Previous signal: r2=37.4 01:26Z Precals 01:35Z Science (1200) 01:58Z Sicence (1200) 02:22Z Science (1500) 02:50Z Postcals 02:56Z Switching to imaging 03:15Z Run 7076. SNe strip 82 S. Skippy happy at frame 11. Focus good at frame 20. Seeing ~1.4" 03:23Z scanStripe: lambda=111.00 03:24Z goDrift: lambda=111.25 03:31Z Ramp start: lambda=113.00, frame 18 03:39Z Science start: lambda=115.00, frame 32 The seeing blew up past 2.3" at frame 58 and to ~3" at frame 80 (so the focus loop was having a hard time, Sir Robert). It dropped to 2" at frame 130 and the focus loop was behaving until around frame 515 when the seeing jumped from 2" to 2.5". 08:34Z Science end: lambda=-171.00, frame 526 08:42Z Ramp end: lambda=-169.00, frame 540 08:43Z Run 7077. SNe strip 82 N. Skippy happy at frame 11. Focus good at frame 22 (we think it was close enough to process, this isn't Legacy imaging). Seeing ~1.6" 08:44Z scanStripe: lambda=-169.00 08:45Z goDrift: lambda=-168.75 08:46Z Ramp start: lambda=-168.50, frame 9 08:54Z Science start: lambda=-166.50, frame 22 11:40Z Science end:
