APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday November 21, 2008 (MJD 54792) ---=== OBSERVING TEAM ===--- Kaike Pan ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- It was a partly cloud night with good seeing. We did spectro. Finshed plates: 3116, (please noticed that three exposures of plate 3116: 56171-173 on mjd 54773 are taken before magnitude problem was fixed). Added signals on plates: 3115, 3160, and 3156(may be done, see log). ---=== OBSERVING LOG ===--- Afternoon: --------- Spectro focus was set for about 3 C (adjusted -2500 on both sp1 and sp2). All systems were checked out and all of them work properly. 23:05Z started ventilation, swaped imager dewar, mounted cartridge 3 for the beginning of night. Night: ------ 00:15Z Started twilight spectra with cartridge 3, plate 3115: Precal frames: 56595-96. Sky spectra: 56597. 00:40Z cart 3, plate 3115 (SEGUE). There were some thin clouds, we decided to do spectro. Fiber 10 was broken on the cartridge. This makes finding FK 5 a little hard. SpiralPatter was used with fiber 9 to get the field. Obtained three 30 min exposures on this plate, but not done yet. 03:05Z cart 5, plate 3116 (SEGUE). SOGTF. This plates has been observed on mjd 54773 and 54774. However, because of magnitude problem in Map files, SoS did not reduce three exposures (exposure #: 56171,56172, 56173) on mjd 54773. We acquired three 30 min exposure. The plate was done with signals from mjd 54773 and 54774.
