Subject: 2.5m obslog 20110512 (MJD 55694) From: asimmons@apo.nmsu.edu Date: Fri, 13 May 2011 11:05:56 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday May 12, 2011 (MJD 55694) ---- Observing Team ---- Kaike Pan Audrey Simmons ---- Observing Summary ---- Clear night, with great seeing. We observed MARVELS fields: Cart 4, plate 4586A Cart 9, plate 4517B - missing 69/70 and 95/96 Cart 6, plate 4814A - missing 15/16, 49/50, 81/82 Cart 3, plate 4823A - missing 107/108, 117/118 Cart 1, plate 4817A Cart 7, plate 4818A - * Cart 5, plate 4681A * - We had to expose on this field twice because Kaike's MJCI session froze right before the readout, causing us to lose the science exposure entirely. See log for more details. ---- Observing Log ---- Afternoon: ---------- Took bias and dark. Mounted cart 4 for the beginning of the night. Checked the telescope. Everything ok. 23:30Z - Started ventilating. Night: ------ 01:50Z - Opened enclosure and filled spectrographs. 02:14Z - gotoField cart 4, MARVELS plate 4586, APGS VOD2.

Seeing 1.5" Kaike's MJCI session froze right before the readout of this exposure (~30 seconds left) and then the program went idle. He noticed that there wasn't any filename associated with the exposure, and his PMT graph window did not update during the next calibration sequence (but Audrey's session was unaffected). This problem caused us to loose this exposure entirely, meaning nothing was read onto the disk. 08:54Z - Cals.
