Subject: 2.5m obslog 20070620 (MJD 54272) Date: Thu, 21 Jun 2007 05:10:19 -0600 (MDT) From: dmbiz@apo.nmsu.edu (Dmitry Bizyaev) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday June 20, 2007 (MJD 54272) ---=== OBSERVING TEAM ===--- Elena Malanushenko Dmitry Brizyaev Shannon Watters (afternoon) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Night was non-photometric. One plate (2744, cartridge 3) is done, other two (2464, cart. 5, and 2564 cart.2) have got some useful signal. Pressure in spectro dewar changes gradually toward low. Dear engineers, please check the spectro dewar in the morning! ---=== OBSERVING LOG ===--- Afternoon: --------- All systems were checked and found working fine. No adjustment made to the spectro focus which is set for ~14C (using cart 2). Night: ----- We had delay in openning because clouds motion was complicated, verga was noticed in the evening. Opened at 4:00Z. Cart 3, plate 2744. This plate has had previous signal s/n=11.6. Used FK5 to find the guide stars. 4:59Z preCalib 5:07 doNextScience 1500 We obtained sufficient signal with s/n=4 and the plate is declared as DONE. Cart 5, plate 2464, segue faint, Priority 4. During setup we had several error messages, including faint flat, can't read "guiderInfo(11,xc)", "no offsets set to tcc from guider" and others. We started/stopped the guider, monitor, tcc, switched to another driver, ran "gotoField -bias" several times, and finally recovered. Later we have found that inspite we stopped the guider before instChange, the guider has not been stopped probably because of very special MAC clicking system. I do not know if this can explain all our problems. Spent 15 min to fix it.

Efficiency is as low as 10%. Next exposure has not been started: waiting for better conditions. 10:05Z - efficiency is still below 15%. Suspicious clouds. Post-cal started. 10:10Z - we decided to close since no acceptable exposure can be done. 10:15Z Telescope closed. 10:28Z endNight is completed. After closing we noticed that spectro dewar pressure is low: 12.3. Pressure builder applied. Pressure is risen up to 18.8 psi. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6859 23:21Z 23:42Z 100 O -31.86 -26.53 50 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 45482, plate -9999 ------- 23:24 45482 0.0 bias ----- sequence 45483, plate 2564 ------- 23:33 45483 10.0 flat 23:36 45484 2.0 arc 23:44 45485 2.0 arc 23:46 45486 3.0 arc ----- sequence 45487, plate -9999 ------- 02:00 45487 0.0 bias 02:04 45488 0.0 bias ----- sequence 45489, plate 2744 ------- 05:02 45489 10.0 flat 05:04 45490 2.0 arc 05:33 45491 1500.0 target ----- sequence 45492, plate 2464 ------- 05:51 45492 10.0 flat - extra flat, taken manually 06:15 45493 10.0 flat 06:18 45494 2.0 arc 06:48 45495 1500.0 target 07:16 45496 1501.0 target 07:44 45497 1501.0 target 08:12 45498 1500.0 target 08:36 45499 1200.0 target 08:40 45500 10.0 flat 08:42 45501 2.0 arc ----- sequence 45502, plate 2564 ------- 08:56 45502 10.0 flat 08:59 45503 2.0 arc 09:28 45504 1501.0 target 10:02 45505 10.0 flat 10:04 45506 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 05:09Z 3 2744 -64.97 -0.0018 58.14 0.0038 127.58 -0.0071 1.000200 06:40Z 5 2464 224.32 0.0003 61.13 0.0025 65.57 -0.0209 1.000130 09:18Z 2 2564 180.08 0.0023 62.73 0.0026 0.07 0.0163 1.000210 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 05:09Z 3 2744 1.00020 -1975 -528 -50 -65 58.1 14.2 13 82 -- 1.7" 06:39Z 5 2464 1.00013 -1284 37 -50 224 61.2 14.8 9 100 -- 1.6" 09:19Z 2 2564 1.00021 -2074 -621 -50 180 62.7 13.7 7 109 -- 1.2" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:11Z 65 41 3 117 (ESE) 510 - 22:43Z 68 45 10 323 (NW) 1013 - 23:15Z 68 44 10 305 (NW) 765 - 23:45Z 65 44 0 214 (SW) 913 - 00:16Z 62 41 14 75 (ENE) 554 - 00:47Z 62 38 9 69 (ENE) 605 - 02:19Z 60 35 19 76 (ENE) 442 - 02:51Z 59 36 20 71 (ENE) 393 - 03:24Z 58 35 17 75 (ENE) 393 - 03:56Z 57 34 15 77 (ENE) 367 - 04:28Z 57 32 19 75 (ENE) 346 - 04:58Z 57 32 16 77 (ENE) 401 - 05:28Z 57 32 14 81 (E) 390 - 05:59Z 57 32 10 89 (E) 390 - 06:31Z 58 31 9 88 (E) 382 - 07:04Z 56 31 8 104 (ESE) 402 - 07:36Z 58 32 7 92 (E) 380 - 08:08Z 56 32 9 93 (E) 429 - 08:41Z 56 34 8 87 (E) 386 - 09:24Z 56 33 7 108 (ESE) 381 - clouds are coming 09:56Z 57 33 7 110 (ESE) 465 - clouds 10:27Z 58 32 5 91 (E) 415 - clouds 10:58Z 59 31 3 107 (ESE) 467 - ---=== TELESCOPE STATUS ===--- 01:45Z Doors opened, fans and blowers on, louvers opened. 04:00Z - Enclosure off. 10:15Z - Enclosure on, doors and louvers closed, fans off.

No responce to click at any window opened at sdsshost2. Driving was immediately shifted to another machine, worked OK. ssh to sdsshost2 and brief inspection didn't show any unusual process. To keep working, Forcequit from landru on X11 was applied. It helped. The problem didn't introduce any delay in observations.
