Subject: 2.5m obslog 20090429 (MJD 54951) Date: Thu, 30 Apr 2009 11:24:31 +0000 (UTC) From: asimmons@apo.nmsu.edu (Audrey Simmons) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday April 29, 2009 (MJD 54951) ---=== OBSERVING TEAM ===--- Howard Brewington Audrey Simmons ---=== OBSERVING PLAN ===--- SEGUE2 Science! ---=== OBSERVING SUMMARY ===--- Clear and photometric all night with excellent seeing. We completed the following plates: Cart 4, plate 3327 Cart 6, plate 3387 Cart 8, plate 3318 And gathered signal on: Cart 5, plate 3386 ---=== OBSERVING LOG ===--- Afternoon: ---------- 23:05Z - Started the afternoon checkout. 23:10Z - There was a slight delay in the checkout while Jon B. worked on Galileo since SOS could not update. 23:35Z - The IDL server is working again, so the checkout was resumed. 23:36Z - Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 118G 18G 88% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 848G 23G 98% /data sdssfiles1p:/data1/data 1.5T 656G 737G 48% /files 23:39Z - Spectro focus was checked but not adjusted. It's set for about 11-degree C, and the collimate numbers are posted in the Problem Section. 23:47Z - Completed the apo_plotbias; results posted in Prob Section. 23:59Z - ARCSAT was made ready for observing, and Eric was notified. 00:15Z - Started telescope checkout; doors/louvers opened, fans turned on. Mounted Cart 04. Afternoon checkout completed. 00:30Z - Started ventilating. We got a weird error message when we started up a watcherClient session, but it didn't effect the watcher at all. This is the message that returned: watch> startClient connected: registered 6 can't read "rtData(daData,archState,id4)": no such element in array can't read "rtData(daData,archState,id4)": no such element in array while executing "set state $rtData(daData,archState,$idNode)..." invoked from within "if {[regexp {(id[1-6])} $node foo idNode]} { set state $rtData(daData,archState,$idNode) set depth $rtData(daData,archQDepth,$idNode) . ..."

Night: ------- 01:52Z - Enclosure off, topped-off spectro secondary dewars, checked top/bottom balance, did a test slew, checked fiducial crossings for each axis, and started the DIMM. 02:05Z - goToField cart 4, SEGUE plate 3327. Used fk5 to find field since we were still in twilight. 02:29Z - Test precals. 02:50Z - Precals. 02:58Z - 30 min exposure.
