APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday June 15, 2008 (MJD 54633) ---=== OBSERVING TEAM ===--- Shannon Watters (observer) Dmitry Bizyaev (observer) ---=== OBSERVING PLAN ===--- Science ---=== OBSERVING SUMMARY ===--- Night was mostly clear but non-photometric, with some clouds, and with a lot of Moon. We added signal to plates 2909 (cart. 8) and 2812 (cart. 7), We replaced a FF lamp (upper right if to look from the back in stove position). The broken lamp is in the engineering trailer on a table in its cartridge in its box. We cannot find guide stars in the fields of seguecluster plates 2632 and 2633, just 2 stars in each field. This was not enough to guide. ---=== OBSERVING LOG ===--- Day: ---- Everything is working ok Collimation set at 16.5C Night: ------ 01:15Z started ventilation, doors and louvers opened. 02:17Z dome opened Cart.8 plate 2909 is on (segue). fk5 used focus loop precal 03:40Z science 1500 04:08Z science 1500 04:36Z science 1500 midcal 05:14Z science 1500 --> 900 postcal -- 06:10Z cart. 7 plate 2812 mounted (segue) fk5 used precal 06:34Z one FF does not work.

Only 2 guide stars are seen after that. We tried large exposure time as well, ~40 sec. Same pisture. -- 10:00Z cart.5 plate 2632 mounted (seguecluster) fk5 used; fk5 is normally seen. Only 3 guide stars are found in the field. One of them is very dim (guider doesn't catch it). Large exposure times ~30 sec 40 sec give the same picture. -- 10:25Z dome closed endNight rejoiced ---=== IMAGING RUN SUMMARY ===--- ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- ---=== LTMATCH RESULTS ===--- ---=== SPECTROSCOPY DATA SUMMARY ===--- 03:31 53671 10.0 flat 03:33 53672 2.0 arc 04:07 53673 1500.0 target 04:35 53674 1500.0 target 05:02 53675 1500.0 target 05:08 53676 10.0 flat 05:11 53677 2.0 arc 05:41 53678 1501.0 target 05:59 53679 901.0 target 06:02 53680 10.0 flat 06:04 53681 2.0 arc ----- sequence 53682, plate 2812 ------- 06:58 53682 10.0 flat 07:01 53683 2.0 arc 07:31 53684 1501.0 target 07:59 53685 1500.0 target 08:29 53686 1501.0 target 08:33 53687 10.0 flat 08:35 53688 2.0 arc 09:04 53689 1500.0 target 09:32 53690 1500.0 target 09:35 53691 10.0 flat 09:37 53692 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- 04:22Z 8 0 -4.82 -0.0016 57.12 0.0056 175.89 0.0104 1.000180 07:07Z 7 2812 52.76 -0.0012 68.94 0.0083 224.91 0.0086 1.000370 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- 04:22Z 8 0 1.00018 -1778 -561 -250 -5 57.1 21.6 3 204 -- 1.0" 07:07Z 7 2812 1.00037 -3654 -2091 -200 53 68.9 19.7 3 345 -- 1.5" ---=== WEATHER LOG ===--- 01:17Z 75 20 7 281 (W) 699 - 01:50Z 73 19 6 270 (W) 732 - some clouds 02:22Z 69 15 5 264 (W) 646 - '' 02:52Z 71 16 3 260 (W) 787 - '' 03:22Z 71 17 1 197 (SSW) 792 - '' 03:54Z 71 16 3 211 (SSW) 779 - '' 04:24Z 70 17 4 212 (SSW) 681 - '' 04:57Z 71 17 2 214 (SW) 699 - '' 05:28Z 70 16 6 224 (SW) 720 - clear 05:59Z 70 16 5 259 (W) 820 - '' 06:29Z 66 15 9 5 (N) 832 - '' 07:02Z 67 14 2 354 (NNW) 763 - '' 07:34Z 69 17 4 352 (NNW) 766 - '' 08:06Z 69 18 7 12 (NNE) 960 - '' 08:36Z 68 17 5 2 (N) 909 - some clouds 09:07Z 68 18 9 40 (NE) 967 - '' 09:38Z 67 21 16 32 (NNE) 901 - '' 10:09Z 67 21 15 51 (NE) 974 - '' ---=== TELESCOPE STATUS ===--- 01:15Z - Began ventilation.
