APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday July 1, 2003 (MJD 52822) ---=== OBSERVING TEAM ===--- swing: Steph Snedden night: Scot Kleinman Atsuko Nitta Gourmet eaters: Jurek, Pete, Howard, John, Jack. Jackie Diehl from Sunspot ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Reasonable Spectroscopy night. We finished 5 plates and got one good exposure on another plate before the clouds thickened and twilight started. Clouds threatened all night, but didn't come until the end (unlike last night, where they didn't hreaten at all, but came multiple times, nonetheless). The manipulator's top height indicator light only works every other time. The beep indicating the manipulator is at the limit is still working and the manipulator stops when it reaches the limit so there is no danger of our damanging it. PR was filed. Gourmet night menu: Assortment of cheese , sundried tomatoes, olives, peppers and crackers. Heavenly Hasty Fresh green salad. Toast with garlic butter. Olives, tomatoes and cheese with capers and herbs. Avocado with sour cream Pink Polish soup (Chwodnic) Mandarin chicken Chicken breasts with artichoke hearts Many grain home-made bread Smoked chicken Jack-size watermelon chocolate covered apricots chocolate covered homeroasted coffee beans (Yemen and Kenya) Blueberry and apple crumble Stuffed baked potatoes ---=== OBSERVING LOG ===--- Swing shift: ------------ Scot & Atsuko had an altitude slip event while they were moving the telescope to remove the imager when lightning started to get too near. The physical position of the telescope was about 87 degrees alt, but the MCP thought it was at 30 degrees alt. Forcing a correction fixed the problem. Later, Steph inspected the alt drive surfaces for evidence of moth, but only a bit of wing at the high altitude end of the drive surface was found. The rest of checkout went without problems, with the exception of the DIMM (see problems section). Night: ------- At sunset, we heard from pete who just arrived that there was rain around Davis Ranch. So we delayed opening. We did see any rain that close to us in the radar, but nothing beats the actual witness's account. 03:15Z We open. We keep an eye on the clouds/rain that is just south of Albuquerque. The clouds are dissipating, but moving south. Cartridge 2 Plate 1330 --------------------------- Used last night's offsets to get FK5 stars. After b1, r1, b2 frames of 21651 were transferred to host, the teamster seemed to have died. We did not see the r2 frame until the second science expsoure (21652) were taken and the teamster started to transfer those frames. We finished this plate in three exposures. Cartridge 5 Plate 1346 --------------------------- Guide stars on gotoField. Finished in 3 exposures. The clouds w/rain and lightening south of Albuquerque is moving SW and breaking up. Cartridge 7 Plate 1392 ---------------------------- Guide stars on gotoField. The clouds and rain are just north of us according to the radar. Finished in 3 exposures. Cartridge 8 Plate 1408 ------------------------------ Guide stars on gotoField. Seeing is getting worse 2.5-3.0" now. The focus sweep plot shows a rather flat trend. We finished this plate in 3 exposures. We had to take postCalib. The clouds moved in while observing this plate. Cartridge 9 Plate 1033 -------------------------- Guide stars on gotoField. Seeing is 2.5-3.0". This plate had previous exposures and only tool one exposure to reach the s/n^2=30. Cartridge 3 Plate 1177 ------------------------ Stars on gotoField.More clouds and seeing is not improving. We will probably not be as efficient in finishing this plate compared to other we have done tonight. We decided to take preCalib after the science to see if it will help avoid having to take postCalib. The clouds thickened and twilight began. We were not able to finish this plate. We only got one useful exposure on this plate. The second science exposure was not good due to clouds. The twilight started so we decided to give up for the night. We closed at 10:30Z. endNight ran happily. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4033 23:07Z 23:13Z 100 O -24.47 -23.01 24 ignore 4034 23:14Z 23:35Z 100 O -22.65 -17.29 47 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): y QA Procedures Done (y/n): y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 21641, plate -9999 ------- 23:06 21641 0.0 bias ----- sequence 21642, plate 1330 ------- 19.9 19.4 21.4 21.0 00:57 21642 10.0 flat 00:59 21643 2.0 arc 01:04 21644 2.1 arc 01:06 21645 2.1 arc 01:21 21646 2.1 arc 01:23 21647 2.1 arc 01:43 21648 0.0 bias 03:50 21649 10.0 flat 03:53 21650 2.0 arc 04:14 21651 900.1 target 04:28 21652 660.1 target 04:42 21653 660.1 target 04:49 21654 240.0 smear ----- sequence 21655, plate 1346 ------- 19.2 17.7 15.9 16.5 05:00 21655 10.0 flat 05:02 21656 2.0 arc 05:22 21657 780.1 target 05:38 21658 780.1 target 05:52 21659 660.1 target 06:03 21660 240.0 smear -----sequence 21661, plate 1392 ------ 18.2 21.2 16.6 19.5 06:16 21661 10.0 flat 06:19 21662 2.0 arc 06:37 21663 720.1 target 06:53 21664 780.1 target 07:09 21665 780.1 target 07:17 21666 240.0 smear ----- sequence 21667, plate 1408 ------- 14.0 14.7 15.7 17.2 07:27 21667 10.0 flat 07:29 21668 2.0 arc 07:52 21669 900.1 target 08:10 21670 900.1 target 08:28 21671 900.1 target 08:36 21672 240.0 smear 08:39 21673 10.0 flat 08:42 21674 2.0 arc ----- sequence 21675, plate 1033 ------- 08:53 21675 10.0 flat 08:55 21676 2.0 arc 09:16 21677 900.1 target ----- sequence 21678, plate 1177 ------- 09:49 21678 900.1 target 09:52 21679 10.0 flat 09:55 21680 2.0 arc 10:15 21681 1020.1 target declared bad ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 04:21Z 2 1330 204.23 0.0049 71.87 0.0039 31.57 0.0206 1.000120 05:08Z 5 1346 241.49 0.0039 56.25 0.0031 87.35 -0.0131 1.000020 06:29Z imager 273.21 0.0061 62.89 0.0022 108.86 -0.0209 1.000020 07:37Z 8 0 267.66 0.0046 53.83 0.0027 109.04 -0.0070 1.000080 09:01Z 9 1033 37.00 0.0029 51.10 0.0010 210.33 0.0154 1.000000 09:32Z 3 1177 12.23 0.0022 48.74 0.0020 190.28 0.0089 1.000500 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL6617 Stays: JL6624 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 04:21Z 2 1330 1.00012 -1184 -103 -250 204 71.9 16.0 11 148 gdr 1.8 05:07Z 5 1346 1.00002 -196 748 -250 241 56.3 15.4 13 138 gdr 1.8 06:28Z 7 1392 1.00002 -196 782 -200 273 62.9 14.1 11 122 gdr 1.8 07:37Z 8 1408 1.00008 -789 315 -200 268 53.9 14.0 6 119 gdr 2.5 09:01Z 9 1033 1.00000 0 978 -200 37 51.1 13.1 8 114 gdr 2.5 09:32Z 3 1177 1.00050 -4936 -3102 -200 12 48.7 13.1 10 155 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:45Z 64 44 5 218 (SW) 671 - 23:18Z 66 43 2 227 (SW) 700 - 23:50Z 68 42 8 206 (SSW) 685 - 00:22Z 65 42 6 194 (SSW) 578 - 00:54Z 66 41 2 191 (S) 660 - 01:27Z 64 41 0 182 (S) 714 - 01:43Z 65 42 2 191 (S) 637 - 02:15Z 63 41 5 181 (S) 670 - 02:47Z 62 41 4 174 (S) 615 - 03:20Z 61 41 11 138 (SE) 614 - 03:52Z 61 40 12 134 (SE) 575 - 04:23Z 60 38 12 143 (SE) 494 - 04:56Z 59 39 13 139 (SE) 463 - 05:28Z 59 38 17 126 (SE) 447 - 05:40Z 58 38 18 125 (SE) 457 - 06:32Z 57 39 6 109 (ESE) 434 - 07:03Z 58 38 7 114 (ESE) 489 - 07:35Z 58 38 10 129 (SE) 501 - 08:05Z 56 38 8 125 (SE) 475 - 08:37Z 55 38 6 161 (SSE) 485 - 09:09Z 55 39 11 142 (SE) 454 - 09:39Z 54 40 11 135 (SE) 552 - 10:11Z 58 39 5 180 (S) 481 - 10:43Z 56 40 8 178 (S) 530 - ---=== TELESCOPE STATUS ===--- 03:15Z: Opened the enclosure. 10:30Z: Closed and fans off.

Since this only seems to happen to the night crew on a regular basis, I suggest one of the day crew be assigned to stay late until a failure is witnessed. Twiddling the alt/dec motion knob made the telescope move again in altitude, although the knob slipped before it engaged again. A PR was filed.
