Subject: 2.5m obslog 20110515 (MJD 55697) From: asimmons@apo.nmsu.edu Date: Mon, 16 May 2011 11:20:46 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday May 15, 2011 (MJD 55697) ---- Observing Team ---- Dan Oravetz Audrey Simmons Craig Loomis (support) Stephane Beland (support) ---- Observing Plan ---- MARVELS ---- Observing Summary ---- Clear night. Poor seeing at first, but then got much better for the last few hours of the night. We observed 7 fields (one twice). We had to switch out the 180L dewer to SP2 during afternoon checkout because it did not have any pressure. It was dewer #5, with a peach cap, showing 4psi on the gauge. The SDSS monitoring graph showed that something very strange happened yesterday after it was hooked up. ---- Observing Log ---- Afternoon: ---------- Checked out telescope. Gathered mirror numbers. Took bias and dark. 01:00Z - Started ventilating. 01:40Z - Filled spectrographs so that we may run tests for Craig during twilight. Night: ------ 02:07Z - Opened enclosure. 02:33Z - Cals.
