APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday April 14, 2010 (MJD 55301) ---=== OBSERVING TEAM ===--- Dan Oravetz Audrey Simmons ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The night was lost due to mostly clouds and humidity. We attempted to take dithered flats for cart 11, but the default time was set to 3 seconds instead of 30. Therefore, the data that we took is not good. It took us two tries to obtain dithered flats for cart 12. In the middle of our first attempt, we encountered a problem where the sp2 cameras did not read out to disk (system froze on 'READING OUT 0.0') and the sequence was aborted. We had to reload the controllers in order to clear the system and restart the dithered flats. We gathered the monthly MARVELS calibrations (except the last two 40 min darks). ---=== OBSERVING LOG ===--- Afternoon: ---------- Found that the tcc actor within STUI was not connected apon arrival. A 'hub startNubs tcc25m' connected it. Telescope checkout went fine. Did not start ventilating due to high humidity, nearby lightning, and some falling raindrops. Night: ------ 02:21Z - 03:30Z Took a bunch of hartmanns in order to focus all blue and red cameras. 03:34Z - 04:07Z Dithered flats cart 11. 04:54Z - Mounted cart 12 for dithered flats. Noticed that the dithered flats taken before with cart 11 are no good because the exposure time was set to the default (which was 3 seconds). 04:56Z - 05:11Z Hartmanns to focus blue and red cameras. 05:14Z - Dithered flats with expTime=30. Exposure sequence aborted after 113349 - sp2 cameras failed to read out. 05:33Z - The bias froze at 'Reading Out 0.0', did not read out sp2 cameras and then aborted itself. We cleared the exposure and reloaded the controllers. The next few biases readout normally. 05:41Z - Reset the motors to their original positions and began the dithered flat sequence again. 113353-74 06:30Z - Turned on MARVELS THAR lamp to prepare for monthly cals. 07:30Z - Began taking MARVELS cals. Finished everything except the last two items - 40 min dark and 40 min dark with shutter open. 08:43Z - Humidity improved. Clouds look thinner. Started ventilation. Mounted cart 16. 09:53Z - High humidity. Stopped ventilating. 10:21Z - There is no chance to open tonight. 10:27Z - endNight finished. ---=== 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 ---=== 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 ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 00:50Z 48 39 3 194 (SSW) 375 - 01:23Z 49 36 9 201 (SSW) 382 - 01:56Z 43 40 18 128 (SE) 511 - 02:29Z 44 38 15 126 (SE) 510 - 03:02Z 44 38 14 133 (SE) 483 - 03:35Z 43 39 15 124 (SE) 501 - 04:08Z 43 37 11 123 (ESE) 444 - 04:41Z 41 37 9 88 (E) 503 - 05:14Z 40 37 13 74 (ENE) 526 - 05:47Z 40 37 4 92 (E) 636 - 06:20Z 40 35 3 193 (SSW) 535 - 06:53Z 41 34 5 92 (E) 509 - 07:26Z 42 34 4 119 (ESE) 440 - 07:59Z 41 33 11 111 (ESE) 385 - 08:32Z 42 32 8 108 (ESE) 294 - 09:04Z 42 31 7 106 (ESE) 390 - 09:37Z 40 34 11 81 (E) 282 - 10:10Z 39 34 10 80 (E) 278 - ---=== TELESCOPE STATUS ===--- 08:44Z - Began ventilation.
