APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday September 22, 2009 (MJD 55097) ---=== OBSERVING TEAM ===--- Dan Oravetz Alaina Shelden Paul Harding (CWRU) Connie Rockosi (phone) ---=== OBSERVING PLAN ===--- Science! Working on guider while doing BOSS science ---=== OBSERVING SUMMARY ===--- SP1B CCD has problems with holding a vacuum and staying cool. We tried filling it several times, and it stayed hovering at -58C. Connie instructed us on disconnecting the full system electronics, and changed voltage settings so that the CCD stays warm relative to the rest of the world. She said that the CCD will warm up to about 30C, and MUST NOT GO HIGHER. We continued with Cart 11 with 3 cameras instead of 4 for the rest of the night. Note: to get the guider vector plot, use the following guider on time=5 plot psPlot display=localhost:15.0 Imaged stripe 79S at the end of the night. lambda position ------------------------------ 177 start focus loop 178 RA=3.2 DEC=7.5 ----> makes sense after 2 scanStripes 179 start ramp, frame 30 -179 start science, frame 38 -169 ramp starts, frame 110 11:30Z -167 ramp stops, frame 122 11:39Z Cart 12 plate 3536 summary Exp type --------------------- 101898 flat 101899 arc 101900-901 science 101902 flat 101903 arc 101907-909 science 101910 flat 101911 arc 101912-913 science Cart 11 plate 3615 summary Exp type --------------------- 101919 flat 101920 arc 101921 arc 101922-924 science 101925 flat 101926 arc ---=== OBSERVING LOG ===--- Afternoon: ---------- 23:53Z Restarted servers. 23:53Z Disk space Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 123G 12G 92% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 805G 67G 93% /data hub25mp:/home 92G 52G 41G 56% /home_hub25m sdssfiles1p:/data1/data 1.8T 62G 1.8T 4% /files 00:01Z Storm coming in from the North, will try to get on sky asap. 00:10Z Afternoon checkout had no problems. 00:38Z Start Hartmanns, exp 101892-894 sp1 sp2 ------------------------------ temp 11.4 10.6 b -4.8 57.3 r -85 -14582 pre motorPosition=-10536,-10948,-10948,33685,32886,33420 post motorPosition=-10536,-10948,-10948,19103,18306,18838 00:50Z Started ventilating 01:09Z Closed doors to rerun collimate--lights were on in dome. 01:09Z Start Hartmanns, exp 101895-897 sp1 sp2 ------------------------------ temp 11.3 10.4 b -6.3 8.9 r 400 -3059 pre motorPosition=-10536,-10948,-10948,19103,18306,18838 post motorPosition=-10536,-10948,-10948,16044,15248,15780 Night: ------ 01:08Z Sunset 01:35Z Opened enclosure 01:42Z Serious boss.SP1ExecBoot Reported by camCheck Waiting to see if the noack will come up again, and then will iack. 01:42Z Slew to field, Cart 12 to begin guiding tests. 01:49Z boss iack 02:13Z All images taken will have command followed by exposures.
