APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday September 22, 2008 (MJD 54732) ---=== OBSERVING TEAM ===--- Dan Oravetz Audrey Simmons Steph Snedden (support) Scott Fleming ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clear night (except around sunset) with moderate/bad seeing. Obtained signal on: Cart 8, plate 3138 (segue) Cart 6, plate 3142 (segue) Cart 5, plate 3030 (marvels) Cart 9, plate 3033 (marvels) Cart 7, plate 3042 (marvels) - DONE Cart 3, plate 3031 (marvels) SOS read out yellow and red NGOODFIBER values for the flat exposures on cart 7, plate 3042. We keep having problems with the murmur due to what we believe are hung processes. It took several attempts to clean, stop/restart, reboot the crates, and once to reboot host2 to fix the problem (see log for more detail). It would be a good idea for either Jon or Fritz to checkout the health of the system to see if they can pinpoint the error(s). ---=== OBSERVING LOG ===--- Afternoon: ---------- The murmur log was not happy because of a hung process that we had trouble locating. We first tried to cleanup the murmur and then stop/restart it without any success. Then we did a hard reboot on the back panels of all of the crates with still no luck. Even rebooting host2 did not help. We did another reboot of the crates and another stop/start of the murmur, and then it worked. Jon should probably checkout the health of the system to stop the murmur log from hanging like this. ad2 monitor is out. Spectral collimation set for ~10C tonight. 00:45Z - Started ventilating, with the doors and louvers open, fans on. Cart 8 mounted. Night: ------ We delayed opening at sunset due to low clouds overhead and large thunderheads nearby. 01:04Z - Sunset 02:21Z - Twilight ends 02:25Z - Opened enclosure to partly cloudy skies. 02:39Z - goToField on cart 8, segue aug08d plate 3138. GSFOGTF. Two -gflats were needed to center the guide stars on the fibers. 02:52Z - Precals. 02:58Z - 25 min exposure. Seeing 1.5" 03:26Z - 25 min exposure. The seeing was ~2.0" the latter half of this exposure. 03:54Z - Mid-cals. 04:05Z - 20 min exposure. Seeing 2.1" (The altitude currently at 42 degrees) This exposure will count for extra signal on the plate, but it will not be included in the total signal. 04:27Z - Postcals. We obtained a total S/N of 8.9 8.8 9.0 8.8 (with extra signal). This plate is not yet done. 04:38Z - Mounted cart 6, segue aug08d plate 3142. Two -gflats used. GSFOGTF. 04:45Z - Precals. 04:53Z - 25 min exposure. Seeing 1.8" 05:21Z - 25 min exposure. 05:49Z - Mid-cals. 05:57Z - 25 min exposure. Seeing 1.6" 06:25Z - Postcals. Total S/N 30.6 18.7 30.4 22.7. This plate is not done yet. 06:30Z - Switched to MARVELS. Mounted cart 5, jun08b marvels commissioning plate 3030. Issued -gflat twice. GSFOGTF. 06:32Z - Calibrations. 06:47Z - Scott started a 40 min exposure. Seeing 1.6" 07:35Z - Calibrations. 07:35Z - Mounted cart 9, jun08b marvels commissioning plate 3033. Used two -gflats. GSFOGTF. 07:45Z - A series of 9 min exposures. Seeing 1.8" 08:15Z - Calibrations. 08:18Z - Mounted cart 7, Marvel-pre aug08ab plate 3042A. Two -gflats. GSFOGTF. Large scale change. 08:38Z - Precals, #54816-17. 08:45Z - 7 sec exposure, #54818. Seeing 2.5" 08:49Z - " " ", #54819. 08:54Z - Took another flat, #54820. The first flat in SOS (#54816) has two yellow values (blue cameras) and two red values (red cameras) of NGOODFIBER. This flat came out the same as the first. Maybe there was a problem with the plate mapping? We took a look at the images visually and saw no problems. We decided to continue exposing on this plate. 08:57Z - 7 sec exposure, #54821 09:02Z - " " ", #54822 09:05Z - " " ", #54823 09:08Z - 12 sec exposure, #54824 09:12Z - " " ", #54825 09:15Z - " " ", #54826 09:18Z - " " ", #54827 09:21Z - " " ", #54828 09:24Z - Mid-cals, #54829-30 09:35Z - goToField plate 3042B.
