APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday November 22, 2007 (MJD 54427) ---=== OBSERVING TEAM ===--- Dan Oravetz (swing) Steph Snedden (observer) Audrey Simmons (observer) ---=== OBSERVING PLAN ===--- Food & Science! ---=== OBSERVING SUMMARY ===--- High humidity, wind, and thick clouds kept us closed all night. We were able to finish dithered flats and imager bias & flats without any problems. Note: The dew point difference reading from weather sensor for the 2.5m on the APO Weather Status Page is not to be trusted. It needs to be looked at (see log for more info). Turkey day menu --------------- Appetizer: Chetter, blue, and brea cheese with crackers Hot queso Delicious hot apple cider Main course: Turkey... baked to perfection Ham Roast beef Potato salad Cranberry salad Buttery biscuits Two bean dishes with french fried onions on top Spiced mashed potatoes and gravy with giblets Squash Pickled beats Cranberry sauce Homemade stuffing Corn Olives Dessert: Five pumpkin pies with whip cream Apple pie Chocolate chip cookies Dembicky family watermelon ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems checked and working properly. As of 21:53Z there are 237G available on /data and 182G available on /files. Spectro focus set for ~0C. Night: ------ Did not ventilate because of high humidity. 02:35Z - Ate turkey. 05:05Z - Note that the current humidity is 95% with a 0.6 dew point difference, but the 2.5m weather senser on the PT read a difference of 5.8 with 65% humidity. We found that it was covered in condensation, so the readings cant be right. It probably needs to be checked. 05:11Z - We decided to take another set of dithered flats. Before we began, we ran another goSpecFoc to set the spectrographs to the current temperature inside in the enclosure (~5.0C). 05:37Z - Started dithered flats. 06:49Z - Dithered flats finished without any errors. Dithered flat exposure numbers: 47521-47535 Arcs: 47536 - 46537 We could have had problems with dithered flats last night because we were ventilating when the temperature was about ~2C. We think that the collimator motors might have had trouble adjusting in the colder temperature and this is what caused the error last night. We should only try to do dithered flats when the temperature is 4C or higher from now on. 06:52Z - We reset the collimation for ~0C. 07:11Z - Mounted imager to start biases and flats. 07:22Z - Started imager on-telescope (tbars unlatched) bias. Run #7191, frames 8-32 07:44Z - Started imager flat. Run #7192, frames 8-32. ----- biasCheck results: Writing file /astrolog/54427/idBiasCheck-007191.par CCD 11 Offset.

Mounted cartridge 3. We decided to leave on the spectrograph dewer at 67 lbs and the imager dewer at 57 lbs since Bob will be in this morning to change them and hook up more dewers to the imager. Steph is on call if there is a problem. 11:39Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7190 21:53Z 22:08Z 100 O 98.86 102.80 40 ignore 7191 07:23Z 07:38Z 100 O -118.24 -114.41 40 bias 7192 07:42Z 07:57Z 100 O -113.40 -109.55 40 calibration ---=== 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 47510, plate -9999 ------- 21:55 47510 0.0 bias ----- sequence 47511, plate 2824 ------- 22:01 47511 10.0 flat 22:04 47512 2.0 arc 22:10 47513 3.0 arc Hartmann 22:12 47514 3.0 arc Hartmann ----- sequence 47515, plate 2309 ------- 23:59 47515 0.0 bias ----- sequence 47516, plate -9999 ------- 00:39 47516 0.0 bias ----- sequence 47516, plate 2309 ------- 05:08 47517 10.0 flat 05:11 47518 2.0 arc ----- sequence 47516, plate 2309 ------- 05:14 47519 3.0 arc 05:16 47520 3.0 arc 05:40 47521 10.0 flat 05:45 47522 10.0 flat 05:49 47523 10.0 flat 05:53 47524 10.0 flat 05:57 47525 10.0 flat 06:01 47526 10.0 flat 06:05 47527 10.0 flat 06:10 47528 10.0 flat 06:14 47529 10.0 flat 06:18 47530 10.0 flat 06:22 47531 10.0 flat 06:26 47532 10.0 flat 06:30 47533 10.0 flat 06:34 47534 10.0 flat 06:38 47535 10.0 flat 06:42 47536 2.0 arc 06:45 47537 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 22:35Z 1 0 1.00000 0 1207 -50 121 30.0 -0.1 0 196 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 20:46Z 29 29 1 138 (SE) 4277 - clouds 21:18Z 33 33 1 210 (SSW) 1260 - clouds 21:50Z 29 29 4 182 (S) 1837 - clouds 22:22Z 29 29 0 163 (SSE) 1573 - mostly cloudy 22:52Z 32 31 2 256 (WSW) 659 - mostly clear 23:22Z 34 30 3 270 (W) 297 - mostly clear 23:54Z 33 29 4 275 (W) 188 - cloudy 00:25Z 33 28 5 269 (W) 197 - " 00:55Z 33 29 6 260 (W) 101 - " 01:25Z 34 29 8 232 (SW) 130 - " 01:55Z 33 29 6 192 (SSW) 168 - " 02:26Z 32 28 6 187 (S) 340 - " 02:56Z 32 29 7 184 (S) 332 - " 03:27Z 32 29 5 178 (S) 330 - " 03:58Z 33 30 5 178 (S) 484 - " 04:29Z 32 30 7 199 (SSW) 870 - " 05:00Z 32 30 2 185 (S) 393 - " 05:30Z 33 32 6 177 (S) 948 - " 06:00Z 32 31 14 175 (S) 676 - " 06:32Z 31 31 13 146 (SE) 668 - " 07:03Z 30 31 14 142 (SE) 3037 - " 07:35Z 31 31 15 167 (SSE) 882 - " 08:08Z 32 32 14 177 (S) 789 - " 08:38Z 32 31 25 187 (S) 893 - " 09:10Z 33 32 26 182 (S) 521 - " 09:41Z 32 28 30 187 (S) 556 - " 10:13Z 32 31 32 184 (S) 607 - " 10:45Z 32 31 30 185 (S) 591 - " 11:17Z 33 28 26 202 (SSW) 1297 - " ---=== TELESCOPE STATUS ===--- We never opened due to bad weather. 11:34Z - Enclosure is on, doors and louvers are closed, and fans are off.
