APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday April 28, 2006 (MJD 53854) ---=== OBSERVING TEAM ===--- Swing: Dan Long Night: John Barentine Viktor Malanushenko Shannon Watters (trainig) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We opened around 7:00Z after waiting foe the weather (humidity, clouds, precipitations) to a reasonable values. We had finished 2 plates and got data on one plate (1729). ---=== OBSERVING LOG ===--- Afternoon: ---------- When taking the afternoon imager bias I saw a 20dn (1740 vs 1760) odd-even effect in r3 bias (shows up as purple on scrolling display). Also saw ~10 dn concurrent bias shifts on the other ccds in dewar 3 (see frames 23 and 24 of run 6115 for example). I don't know if this is really a problem, but it isn't what I usually see in a bias. 21:00Z Rain sensor went off. It is currently disabled. Adjusted focus of spectrographs for today's much cooler temperatures. They were set for about 8 C, now set for about 3 C. See problems section for details.
