APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday March 10, 2006 (MJD 53805) ---=== OBSERVING TEAM ===--- Steph Snedden Jian Ge and the ET crew Support: French Leger Jim Gunn Connie Rockosi Visitors: Kaike Pan ---=== OBSERVING PLAN ===--- ET setup and science ---=== OBSERVING SUMMARY ===--- ET fine tuning continued. We are ready to go on the sky whenever the weather lets us. Tonight, the weather didn't cooperate. ---=== OBSERVING LOG ===--- No swing shift for ET time. High winds and dust at sunset. Orographic clouds started forming during twilight. 01:20Z Watcher's Micro, System and Volts panes lit up like a Xmas tree. Sure enough, Jim had swapped in a micro, and was able to talk to the imager. The imager talked back to the Watcher. It's a rare occurance when I am happy to see red Watcher panes. 03:00Z Unmounted the imager and put it in the doghouse. Mounted ET cartridge 1, plate 8019. Still windy, dusty, cloudy. As of this afternoon, the following plates have been mounted to cartridges: Cart Plate ---- ----- 1 8019 5 8020 6 8021 7 8022 8 8023 All the plugMap files have the correct cartridges identified, so loadCartridge should work. 07:12Z Clouds and wind have settled down, but we are still waiting on dust, and are watching the dewpoint depression shrink >:-( 11:58Z We give up. endNight finished. ---- Notes for dealing with ET cartridge changes: The ET science fibers come up out of the cone area through a hole in the plate on the floor a little forward of the doghouse and mount to the back of the cartridge. The ET crew should attach the fibers to the cartridge, not the observer. 1. When umounting a cartridge, one of the ET crew will disconnect their three fiber bundles from the sockets on the back side of the cartridge. 2. The fibers are also protected from strain with a piece of duct tape near the bottom of the cartridge. Carefully remove the tape. 3. Cap the fiber ends. 4. Carefully feed the fibers down the hole in the plate until all three bundles are recessed into the plate. 5. You should then cover them with the round swivel plate before rolling the cart into place under the telescope. 6. The cartridge can then be removed just like a regular survey cartridge. To mount a cartridge, you pretty much reverse the proceess: 1. Make sure the fibers are completely recessed into the floor plate and covered by the swivel plate. 2. Roll the cartridge under the telescope and mount as usual. 3. Roll the cart away. 4. Uncover the fibers and gently pull them out. They will fit into the slot in the swivel plate once you have pulled them out past the strain relief cover. 5. Uncap the fibers. 6. Have the ET crew attach the fibers to the cartridge. 7. Secure the fiber bundles near the bottom of the cartridge with duct tape. Avoid straining the bundles, 8. It's a good idea to have someone from the ET team watch the fibers from a safe place near a stop button when you goToField. If it looks like the fibers might catch on something or get strained, they can hit a stop button. They SHOULD NOT try to go to the fibers. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== 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 37999, plate -9999 ------- 23:13 37999 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL Stays: JL ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:32Z 38 12 41 256 (WSW) 5003 - 23:03Z 37 11 32 241 (WSW) 5334 - 23:35Z 36 12 23 267 (W) 4566 - 00:07Z 36 13 20 243 (WSW) 4278 - 00:39Z 34 12 32 265 (W) 5451 - 01:11Z 32 11 30 251 (WSW) 5163 - 01:43Z 32 13 39 255 (WSW) 5075 - 02:15Z 32 14 33 267 (W) 4908 - 02:48Z 32 16 29 241 (WSW) 3886 - 03:20Z 31 16 32 262 (W) 4292 - 03:52Z 31 15 29 234 (SW) 4503 - 04:24Z 30 14 21 242 (WSW) 5864 - 04:56Z 30 17 29 249 (WSW) 5401 - 05:30Z 29 17 24 265 (W) 3698 - 06:02Z 28 17 25 255 (WSW) 2865 - 06:33Z 27 17 21 254 (WSW) 2777 - 07:05Z 26 17 20 249 (WSW) 2861 - 07:37Z 25 19 19 264 (W) 2842 - 08:07Z 25 18 21 253 (WSW) 2747 - 08:37Z 25 17 22 251 (WSW) 2770 - 09:07Z 25 17 27 258 (WSW) 2445 - 09:38Z 24 17 28 250 (WSW) 2506 - 10:08Z 24 18 18 267 (W) 2416 - 10:40Z 24 19 22 258 (WSW) 2453 - 11:12Z 23 19 18 266 (W) 2367 - 11:45Z 24 20 22 263 (W) 2326 - ---=== TELESCOPE STATUS ===--- 11:59Z Telescope stowed at zenith, counterweights fully down, pin in.
