APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday February 27, 2009 (MJD 54890) ---=== OBSERVING TEAM ===--- Howard Brewington Dmitry Bizyaev Kaike Pan (swing) ---=== OBSERVING PLAN ===--- SEGUE Science all night long ---=== OBSERVING SUMMARY ===--- The control room stop button problem was fixed, but we got telescope later bacause of this. The night was partly cloudy, bad seeing after ~ 08 Z because of the wind direction change. Got signal to plates: 3231 (c.6) done 3165 (c.4) finished Marvels pre 3233 (c.8) 3244 (c.2) 3236 (c.1) ---=== OBSERVING LOG ===--- Afternoon: ---------- E-Stop bottom in the control room stope work properly at about 1:30Pm today. Dan and wendell are working on it. while they are working the E-stop, we checked spectro focus and other stuff. The best focus is set for about 8.5 C. 00:20Z started ventilation. 01:20Z Engineering crew returned us the telescope.
