APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday June 5, 2009 (MJD 54988) ---=== OBSERVING TEAM ===--- Elena Malanushenko Audrey Simmons Viktor Malanushenko (afternoon setup) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We lost the first half of the night to clouds. We obtained exposures on the following MARVELS plates: Cart 3, plate 3414A&B Field A, broken: 53/54, blue #7, blue, yellow, #27 Cart 8, plate 3489B Field B, possible broken: 71/72, green #16, red, orange, #108 Cart 6, plate 3495 We lost ~40 minutes of science time because the guider stopped updating. ---=== OBSERVING LOG ===--- Afternoon: ---------- All system checked and worked good. The first bias, 61550 has been mark as 'bad' i.e. b2 and r2 more than 65000. The next bias, 61551 - good. Flat 61552 and arc 61553 are looked good. Checked the spectro collimation for cart 6, plate 3495 but did not adjust them. They are set for a temperature of ~12C. 02:10Z - Began ventilating. Mounted cart 1, plate 3280 for the beginning of night. Night: ------ Did not open at sunset due to thick clouds overhead. 02:06Z - Sunset. 03:47Z - Evening 18-degree twilight. 04:58Z - Stopped ventilating because of high dust counts (~3100). 05:50Z - Opened enclosure and started ventilating. Mounted cart 3, MARVELS plate 3414. We did not fill the spectrographs. *** 05:58Z - Calibrations.

Used fk5. 08:40Z - 50 min exposure. Alt 72 degrees, seeing 1.3". Had to abort the exposure 12 minutes into the exposure because the guider stopped working. There was an error in SOP complaining that the guider could not guide on fiber 6. We disabled the fiber and basically started over, by going back to the field and issuing another gflat, and then the guider was happy again. 09:16Z - 50 min exposure.

Did not find guide stars, nor fk5, until it was noticed that the rotator axes were halted.
