APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday September 25, 2010 (MJD 55465) ---=== OBSERVING TEAM ===--- Audrey Simmons Howard Brewington Support: Paul Harding (on site) ---=== OBSERVING PLAN ===--- MARVELS Science! ---=== OBSERVING SUMMARY ===--- For the most part, the night was lost to clouds and high humidity. We did, however, open for a short time to do Paul's collimate tests and completed part of a marvels exposure. Wind was from the east and seeing was 2.5 to 3" during the 25-minute marvels exposure. We are still geting MARVELS alarms, e.g., Sat Sep 25 17:14:05 MDT 2010 Error: ALARM> ch-6 : Bottom = 27.929 < 27.93 C ---=== OBSERVING LOG ===--- Afternoon: ---------- 22:30Z Arived on site. 22:45Z Started the checkout 22:55Z Recorded and checked the mirror numbers 23:05Z Turned on MARVELS ThAr lamp 23:12Z [hjbrew@sdsshost2 notes]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 134G 777M 100% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 692G 179G 80% /data hub25m-p:/home - - - - /home_hub25m sdssfiles1-p:/data1/data 1.8T 157G 1.7T 9% /files [observer@hub25m-p ~]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 95G 22G 69G 24% / /dev/sda4 793G 97G 655G 13% /home /dev/sda1 99M 19M 75M 20% /boot tmpfs 5.9G 0 5.9G 0% /dev/shm /dev/drbd1 13T 2.3T 11T 19% /data 23:14Z Error: ALARM> ch-6 : Bottom = 27.929 < 27.93 C 23:20Z Recorded the software versions 23:25Z Checked the actors 23:30Z Did 'platedb showActive' MARVELS carts 1, 3, 4, 5, 6, 7, 9, are ready. 23:32Z Checked gcamera status.

Night: ------ 00:56Z Sunset with increasing humidity. 01:20Z Enclosure off, topped-off spectro secondary dewars, checked top/bottom balance, did a test slew, and checked fiducial crossings for each axis. 02:06Z We have the ENGCAM mounted since Paul Harding wants to do a couple of quick collimation tests. The seeing is very bad, so we went ahead with Paul's tests. 02:42Z Cart 01, plate 4100, MARVELS, pointing B, seeing was about 3" because the wind is from the east. A small storm system is moving to the site from the northeast. The science exposure was aborted after 30 minutes because of nearby radar return.
