APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday May 1, 2005 (MJD 53492) ---=== OBSERVING TEAM ===--- Jurek Krzesinski John Barentine Gourmet Night Diners: Scot Kleinman Atsuko Nitta Russet McMillan Mike Harvanek Jackie Diehl Bruce Woodgate (GSFC) Carol Grady (GSFC) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We spent most of the night under thick clouds. Acquired signal on one plate (1575) but did not finish it. Gourmet Night Menu ------------------ Mushroom Soup New Mexico-style Red Chile Cheese Enchiladas Spinach, Chicken and Alfredo Lasagne Dirty Rice with Shrimp Spicy Corn Bread Spinach Salad Roasted Chicken with White Wine and Orange Reduction Mudd Pie Vanilla Ice Cream with Two Toppings: Fresh Bananas Fresh Strawberries with Balsamic Glaze Dove Dark Chocolate Steph's Coffee ---=== OBSERVING LOG ===--- Afternoon checkout: ------------------ Since we were overcast, we waited with spectrographs focus check till late night, the temperatrue was quite stable all the time (~9 C.) ~06:20Z sp1 was out of focus. Focus corrected (mechpistonned + b1 ring moved, xmin corrected, more details in the problem setion). We have nothing to report on the checkout. Night: ------ We elected to open just after 08:00Z as the clouds thinned a bit. 08:16Z Cart 4 Plate 1575 (tile 1113, chunk76). GSOGTF but the clouds immediately conspired to drop our efficiency to zero during the setup. We then had stars intermittently. We used the time to double- check spectrograph focus with the new plate to see if the previous efforts came to anything; everything checks out okay. Started a 1200 s exposure to see if we would get anything through the clouds. We got some signal on this and a subsequent 1500 s exposure, but had to keep upping the exposure times to compensate for increasingly thick clouds. Finally we quit 1145 s into an 1800 s exposure when efficiency pegged at zero, though we read out early and kept what signal we had acquired to that point. The cloud situation didn't improve before twilight. We closed at 10:55Z. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5299 00:05Z 00:25Z 100 O -69.45 -64.55 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): yes QA Procedures Done (y/n): yes UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 00:26 32408 0.0 bias ----- sequence 32409, plate 2012 ------- 01:09 32409 10.0 flat 01:11 32410 2.0 arc 01:20 32411 0.0 bias 02:07 32412 10.0 flat 02:10 32413 2.0 arc 03:46 32414 10.0 flat 03:49 32415 2.0 arc 05:02 32416 10.0 flat 06:04 32417 2.1 arc 06:06 32418 2.1 arc 06:20 32419 2.1 arc 06:22 32420 2.1 arc 06:46 32421 2.1 arc 06:48 32422 2.1 arc 06:57 32423 10.0 flat 07:00 32424 2.0 arc 07:15 32425 10.0 flat 07:17 32426 2.0 arc 07:23 32427 2.1 arc 07:25 32428 2.1 arc 07:34 32429 10.0 flat 07:37 32430 2.0 arc 07:50 32431 10.0 flat 07:52 32432 2.0 arc 08:02 32433 2.1 arc 08:04 32434 2.1 arc ----- sequence 32435, plate 1575 ------- 9.6 7.7 12.2 9.3 08:44 32435 10.0 flat 08:46 32436 2.0 arc 09:11 32437 1200.1 target 09:39 32438 1500.1 target 10:01 32439 1145.0 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 08:51Z 4 1575 -20.13 -0.0001 82.29 0.0009 161.17 0.0457 1.000100 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL8475 Stays: JL8476 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 08:52Z 4 1575 1.00010 -988 359 60 -21 82.3 7.2 11 270 -- 1.3 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 00:23Z 50 16 15 224 (SW) 601 - Overcast 00:56Z 49 15 11 238 (WSW) 529 - Overcast 01:28Z 49 14 10 248 (WSW) 523 - Overcast 02:01Z 49 13 11 235 (SW) 546 - Overcast 02:32Z 48 14 12 243 (WSW) 555 - Overcast 03:04Z 49 12 3 265 (W) 506 - Overcast 03:36Z 49 11 2 262 (W) 521 - Overcast 04:07Z 48 11 6 273 (W) 502 - Overcast 04:37Z 48 12 3 293 (WNW) 523 - Overcast 05:11Z 48 12 7 275 (W) 494 - Overcast 05:42Z 48 8 8 299 (WNW) 522 - Overcast 06:14Z 48 11 12 300 (WNW) 561 - Overcast 06:46Z 47 8 15 282 (WNW) 573 - MstlyCldy 07:19Z 46 9 12 278 (W) 599 - PtlyCldy 07:51Z 46 10 11 288 (WNW) 572 - PtlyCldy 08:40Z 45 13 8 269 (W) 580 - PtlyCldy 09:12Z 44 15 6 273 (W) 547 - PtlyCldy 09:44Z 44 14 8 273 (W) 557 - MstlyCldy 10:18Z 44 15 8 269 (W) 566 - MstlyCldy 10:50Z 43 18 5 265 (W) 543 - MstlyCldy 11:21Z 42 19 7 264 (W) 545 - ---=== TELESCOPE STATUS ===--- 01:20Z Doors opened, fans on. 08:10Z Enclosure off 10:55Z Enclosure on, fans off, louvers and doors closed, Spectro dewars force-filled Telescope parked at 121,30 with Cart 4 (Plate 1575) mounted Counterweights at 270 Spectro autofill reconnected No interlocks bypassed Dewar weights at 11:15Z Imager: 215lbs 16psi Spectro: 105lbs 22psi ---=== SOFTWARE USED ===--- IOP/SOP: v3_147_0 Watcher: v2_30_0 MCP: v5_26_0 TPM: tpm_v2_47_0 AstroDa: v14_47 TCC: TCC 2.7.2.1 August 6 2004 sdssProcedures: v2_01 SoS: v4_10_7 hoggPT: v1_6_9 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A 0.5820 0.5770 Axial B 0.5870 0.5880 Axial C 0.9480 0.9460 Trans D -8.1960 -8.1960 Lateral E 10.0457 10.0330 Lateral F 11.5951 11.5951 GALILS Commanded: 4300. -1900. 2850. -13300. -7600. -7650.
