Observers: G. De Rosa, S. J. Schmidt Telescope Operator: S. Allenson Support Astronomer: M. Edwards Instrument: LUCI (cals with MODS and LBC) Summary: N3.75 LUCI camera problem fixed during the day. We opened the dome at UT 0:10 and took H-band LUCI skyflats at UT 0:35. NOTE: we forgot to change OBJECT keyword, for skyflats OBJECT=your object. We started with ND_ptf11kkx_ir, but due to its high airmass, we only obtained H and K bands, not J (also, AGW was struggling due to atmospheric distortions). For the next several hours, our target choices were dictated by both the position of the moon and poor + variable seeing (1.4" - 2.2" for most of the night). Our next targets were OSU_UCDz/SL00109A and SL00109B (with a shared telluric standard). At UT 3:55, we moved to OSU_BALQSO_He/SDSSJ0250+0009, nearly doubling the exposure time due to bad seeing and OSU_BALQSO_He/SDSSJ0809+25 (also with a nearly doubled exposure time). A guiding failure at UT 11:15 prevented us from obtaining the last telluric standard for SDSSJ0809+25 until the after error was recovered at UT 11:35. The seeing improved significantly (1"-1.1" in the optical), so we observed OSU_Lensmass/SDSS0924. Dome closed at 13:15. Weather: Clear, humidity at ~30%. Weather stable all night. Bad seeing (1.5"-2.2") between 03:45 and 11:45. Bright sky for two thirds of the night. LBC calibrations: Bias (25 frames) -- bias frames ha UT date 20121123 MODS calibrations: slitflats (0.3",0.6",0.8"), dual grating LUCI UT 00:35 Skyflats: H band (11) NOTE: we forgot to change OBJECT keyword, for skyflats OBJECT=your object UT 01:00 collimating, guiding stable ND_ptf11kkx_ir UT 01:02 slewing to target (wrong acquisition script: wrong mask ID; no mask ID needed in imaging) UT 01:03 ran acquisition script again, seeing J-band ~0.8" UT 01:20 K-band imaging script (the source is at very low airmass, program requires good seeing, and the sky is dark enough to start) seeing ~0.9", PSF elongated due to vignetting Changed guide star for next observations Given that the target is setting quickly, we will try to get H & J with the new guide star UT 01:40 run acquisition with new guide star Clear up optics - try to collimate Situation better than before, but AGW is struggling due to atmospheric distortions (object too low in elevation) UT 01:53 -- H band seeing on image ~1.2", we are having issues meeting the IQ requested by the PI due to the low elevation of the target. NOTE TO THE PI: please check images and let us know if it would be of any use to complete the observation in J band. UT 02:06 move to zenith to switch camera (N3.75 -> N1.8) OSU_UDCz/SL00109A UT 02:10 target acquisition, guiding star too faint given moon illumination. Changed guide star to bright star (option already in the script) UT 02:18 science script _zJ UT 02:30 guider seeing highly variable 1"-1.6" Quick extraction of the spectrum to check S/N (OK) UT 02:39 science script_HK -- guider seeing 1.1"-1.2" UT 02:47 slewed to standard UT 02:59 started standard spectrum HK UT 3:02 started standard spectrum zJ OSU_UDCz/SL00109B UT 03:07 -- acquisition UT 03:17 -- science spectrum zJ -- guider seeing 1"-1.1" UT 03:36 -- science spectrum HK -- guider seeing 1.1"-1.2" UT 03:45 -- guider seeing variable ~1.1"-1.5" @ airmass 1.372 OSU_BALQSO_He/SDSSJ0250+0009 NOTE: given observing conditions we have repeated the script longer as required by the PI UT 03:55 Telluric standard (Hip10512) UT 04:03 first set of exposures was nonlinear, we changed DIT and NDIT to avoid nonlinearity problems in guiding due to moon brightness + bad seeing UT 04:30 start first set of exposure (seeing 1.5-1.8, difficult guiding due to moon brightness: source 30 deg away from the moon) NOTE: seeing does not match the PI requests, but it is the only object visible that is sufficiently far away from the moon and does not need high resolution (just signal). We will run script more times than requested to build up additional signal. UT 05:15 seeing highly variable 1.6"-2." UT 05:20 second set of exposures UT 05:36 Technical issue with primary mirror, integration aborted (we got 6 out of 17 exposures) Recovered by 5:42, then waited for collimation before slewing (as target guide star is faint). UT 5:45 slewed to HIP10512 (standard) UT 5:53 started telluric spectrum UT 6:00 slewed back to SDSSJ0250 (DIMM seeing 1.8", guider seeing 2"-2.5", difficult to center object on slit) UT 6:12 started science obs UT 06:20 average DIMM seeing varying between 1.5" and 2" UT 06:57 started another series of science obs UT 07:40 slew to telluric standard UT 07:48 started telluric exposures (changed 12 DIT to 4 DIT 3 NDIT to avoid non-linearity) NOTE TO THE PI: please check data quality OSU_BALQSO_He/SDSSJ0809+25 NOTE: given observing conditions we have repeated the script longer as required by the PI UT 07:53 slewing to beginning standard Hip35345 (changed acquisition script for a brighter guiding star, PA=180) UT 08:00 average seeing ~1.8" UT 08:01 began standard exposures UT 08:07 slew to target -- acquisitions -- seeing from guiding star variable 1.5"-2" UT 08:16 started series of exposures on target UT 08:47 average seeing from guiding star 1.8"-1.9" UT 09:00 started another series of exposures on science target -- average seeing 2.1"-2.5" UT 09:44 slew to standard (HIP35345) UT 09:51 spectra of standard -- average seeing 1.8" UT 09:56 slew back to target UT 10:08 start another series of exposures on science (seeing variable between 1.3"-1.8") UT 10:52 another series of exposures on science UT 11:05 AGW technical issue, guiding failure UT 11:35 failure recovered, slewed to HIP35345 UT 11:45 telluric spectrum NOTE TO THE PI: please check data quality UT 11:52 seeing improved dramatically 1" -1.1" in optical (guiding), try to get OSU_Lensmass/SDSS0924 acquisition script, wrong mask! UT 12:07 science exposure J band 1st exposure, average seeing in optical 1"-1.2" (guiding star) 2nd exposure, average seeing in optical 1" 3rd exposure, average seeing in optical 0.8" NOTE: data were taken at the end of the night with a 600 DIT exposure in J, we note a significant amount of persistence in the images. We see a double trace in the differential images. UT 12:40 science exposure HK-- average optical seeing 0.8" (Spectra look great) UT 12:53 slew to telluric standard UT 13:00 telluric spectrum J -- notice that there is only one exposure(??) -- modify script to add dithering UT 13:05 telluric spectrum HK modified, with dithering UT 13:10 telluric spectrum J modified, with dithering UT 13:15 Dome close
