Subject: 2.5m obslog 20151226 (SJD 57383) From: dmbiz@apo.nmsu.edu Date: Sun, 27 Dec 2015 10:32:57 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday December 26, 2015 (SJD 57383) ---- Observing Team ---- Gordon Freischlad Dmitry Bizyaev ---- Observing Summary ---- Weather conditions: cloudy sky, steady wind up to 67 mph, wind gusts up to 81 mph, high humidity (up to 93%), low temperature (down to -14C), blowing snow. We weighted a possibility to open and decided to stay closed. The whole night (12.1 hours) was lost due to the weather. Electric power cut in the middle of the night. Site is on generator power since 07:57Z. Problems: 3 rather large trees fallen, one near the Lindy cart shed, two more close to the truck parking space. No visual damage to the infrastructure objects is seen. Some snow blew under the East rolling door. We cannot safely remove it during the night, but it's not going to melt down. ---- Observing Plan ---- Sat 26 DEC 2015 57383.0 0.98 01:03 13:07 00:20 12:26 Night APOGEE-2 (12.1 h) ---- Observing Log ---- =============== Afternoon =============== All systems alive and responding normally. motorPosition sp1: 21800, 22121, 21831; sp2: -1702, -2459, -2182; ---------- Median spectrographs temperatures: Tsp1= 3.0, Tsp2= 2.6; Outside air temperature= -9.3; 23:21:55 Hartmann collimate output on cart #3 sp1: offset: r= -1319 (Out of focus); b= 0.8 (In Focus) sp2: offset: r= -631 (In Focus); b= 2.8 (In Focus) sp1: pred. move: spAverageMove= -788 sp2: pred. move: spAverageMove= -756 sp1: pred. spResiduals: r= -531, b= -1.7, txt= OK, spTemp = 2.9 sp2: pred. spResiduals: r= 125, b= 0.4, txt= OK, spTemp = 2.6 It is snowing rather hard so ventilation was not started and cart 3 was left on the telescope. ======== Night ======== Severe weather conditions.
