Subject: 2.5m obslog 20080413 (MJD 54570) Date: Mon, 14 Apr 2008 05:41:54 -0600 (MDT) From: asimmons@apo.nmsu.edu (Audrey Simmons) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday April 13, 2008 (MJD 54570) ---=== OBSERVING TEAM ===--- Dan Oravetz Audrey Simmons Jon Brinkmann (support) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clear but with the occasional bad seeing. Gained signal on: Cart 7, plate 2859 (an email was sent to Brian Yanny, asking if this plate is done or not) Cart 6, plate 2446 Finished: Cart 4, plate 2461 Cart 9, plate 2522 Cart 2, plate 2519 The cloud camera worked for the first 1.5 hrs it was open, and then it unexpectedly shut off. We contacted Jon. Power cycling the camera by putting on the cover and then taking it back off again seemed to fix the problem. We had no further problems the rest of the night. The ad3 monitor in the control room does not work. ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems checked and working properly. 17:55 sdsshost2.apo.nmsu.edu % df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 134G 853M 100% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 595G 276G 69% /data sdssfiles1:/data1/data 1.5T 531G 862G 39% /files Both spectrographs are set for a night temperature of 3.5C (see problem section for more detail). The ad3 monitor is out in the control room. 00:35Z - Started ventilating with the doors and louvers open, fans on. Mounted cartridge 7. Night: ------ 01:40Z - Opened enclosure to clear skies. 01:59Z - goToField cart 7, segue169 plate 2859. Used fk5 to find field since the sky was still bright out. 02:38Z - Precals. Red and yellow values returned for the flat and the arc. The mirror temps were slightly warmer than the ambient (2.5C outside), and the spectrographs were currently at a temp of 6.6 and 4.8. We dont understand why the collimation would be out of focus a these temperatures. We mechPistoned both spectrographs +2500 to try to adapt to the current temperature differences. 02:40Z - Precals, attempt #2. The flat returned three yellow values, while the arc returned two. We mechPistoned an additional +1500 for both spectrographs, and tried again. The spectrographs were now set for a temperature of 7.5C, when the outside temp was 2.5C. 02:51Z - Precals, attempt #3. SOS returned all black values. Current outside temp: 4.0C 03:01Z - 25 min exposure. Seeing 2-3.0" (low altitude - 35 degrees) (S/N)^2 -> 01 1.0 0.8 0.7 (with one red sky value) We do not know if this exposure is useful or not - Brian will verify this later. 03:32Z - Mounted cart 4, seguefaint140 plate 2461 GSFOGTF. 03:39Z - Precals.
