Subject: 2.5m obslog 20080701 (MJD 54649) Date: Wed, 2 Jul 2008 04:29:09 -0600 (MDT) From: snedden@apo.nmsu.edu (Steph Snedden) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday July 1, 2008 (MJD 54649) ---=== OBSERVING TEAM ===--- Viktor Malanushenko Steph Snedden Dan Oravetz (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds, rain lightning with a couple of brief sucker holes. We did QE measurements on g6 and i4 The spectro dewar needs to be changed sometime during the day. ---=== OBSERVING LOG ===--- Afternoon: --------- All systems checked and working properly. The Telescope Coolant Pump Circulation gauge is no longer reading zero. sdsshost2.apo.nmsu.edu % df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 132G 2.9G 98% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 638G 233G 74% /data sdssfiles1:/data1/data 1.5T 631G 762G 46% /files Spectro focus set for ~13C (sp1) and ~12C (sp2). Cartridge 3 is mounted. Night: ----- 03:16Z - After waiting for lightning to move out of the area we set up for MSP calibrations. During the QE on g6, a sucker hole opened, but there were storms approaching and shortly after the hole opened, humidity went past closing conditions. The g6 images show several small round defects, one larger round darkish spot and a strange oval spot on the CCD. The spots are darker than the nearby illuminated CCD by about 4 percent. Jim wants us to do some goStares with the imager mounted and using the imager flat lamps to see how the spots look then. The details of the test request will go into the science plan. Photodiode voltage variations were within tolerance - they are detailed in the problems section at the end of the log.
