APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday February 17, 2007 (MJD 54149) ---=== OBSERVING TEAM ===--- Observers: Viktor Malanushenko Elena Malanushenko ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Mostly clear for whole night and only not good seeing and light cirrus stopped us from imaging and we observed spectra. Four plates are done (2423,2332,2488,2602); 2689 plate needs special review from Brian Yanny (please, check it); and one plate (2548) has good signal. Our telescope was working good for us. ---=== OBSERVING LOG ===--- Afternoon: ---------- Telescope has been prepared for night. Spectro has been adjusted to expected night temperature +1C. All systems works fine. We only mentioned red blinking light and some sound on circulations panel in low enclosure. Also we saw red light on some boards inside pannel. Steph suggested us to continue observations and research the problerm late. We did not find any useful information about this alarm. Nigh: ----- Clear, but some clouds in Valley and on South.

We observed this plate with long exposure (1500 sec) at good weather condition. No way to obtain the significantly better signal in b1 camera. We desided do not declare exposures as "bad" and continue the observations using b2 s/n value as a criteria. We obtaines s/n=32.7 and guess the plate is DONE. We need Brian Yanny's opinion about this plate.
