OSU/RC Queue Observing UTC 2011 Dec 29 (civil date 2011 Dec 29/30) =========================================== Observers: BShappee & ERyan Observing Assistant: Support Astronomer : DThompson Instrumentation : Instrument: LBC Summary: Slight high Cirrus mostly on the horizon to the north. Seeing ~0.5-0.8. Object/field completed: OSU_qso/0959 ri image observed to complete the field Program UM_hildas completed: Observer at telescope choose to sacrifice/replace OB for 2004 VU53 to do Comet 2011 Y2 Boattini Tested non sidereal tracking and had no problems with comets moving in excess of 100 arcseconds per hour, images showed very clear stellar trails and fixed comet Non-sidereal tracking proceedure may update in near future, however the support astronomer should know how to do this for future UM moving target programs Details: 25 Biases taken/ skyflats in 2 position angles, 5 point dithering Uspec r first set the r sloan is saturated in the first couple exposures at minimum exposure time (free Uspec flats), we then re-ran the flats at position angle 0 ~01:20: slew to WT10_276 to collimate Red Convergence reached for seeing of 1.03663 arcsec. Blue Convergence reached for seeing of 1.43817 arcsec. 01:27: co-pointed (twice just to make sure because the first one was large and the sky is still a little bright) 01:35: slew to science field (commet 2006t1 levy) to collimate close to targe (again we have spare time) Red Convergence reached for seeing of 0.841440 arcsec. Blue Convergence reached for seeing of 1.35358 arcsec. 01:41: OB 2006T1Levy_dec2011 01:47: stopped OB because the first exposure showed that the telescope was jumpy This that it was due to LBC trying to guide, so reset OB with tracking off in LBC Now star trails look nice and even 02:00: 2011Y2 collimation: Red Convergence reached for seeing of 0.695860 arcsec. Blue Convergence reached for seeing of 1.21253 arcsec. ~02:27: OB 2003sl159 (mis-labeled target name is 2003sl259) collimation: Red Convergence reached for seeing of 0.609236 arcsec. Blue Convergence reached for seeing of 1.05366 arcsec. 02:44: OB J0613 standard Red Convergence reached for seeing of 0.893311 arcsec. Blue Convergence reached for seeing of 1.27466 arcsec. blue seeing ~0.8-0.9 red seeing ~0.65 02:57: UM_Hildas/kenlevin_dec2011 collimation: Red Convergence reached for seeing of 0.666339 arcsec. Blue Convergence reached for seeing of 1.06082 arcsec. 03:15: UM_Hildas/BHG88 collimation: Crowded collimation field so be waery of collimation Red Convergence reached for seeing of 0.974958 arcsec. Blue Convergence reached for seeing of 1.33976 arcsec. 03:30: UM_Hildas/GCS1227 Collimation: Red Convergence reached for seeing of 0.904879 arcsec. Blue Convergence reached for seeing of 1.02443 arcsec. ~03:45: ND_WHIM/SA95 Collimation: accdentally aborted dofpia OB, cause idl script to hang, it timed out. Re-ran the script but still hung on same place looking for output files. In idl ran .reset to reset session, then ran dofpia and it worked properly. Red Convergence reached for seeing of 0.883734 arcsec. Blue Convergence reached for seeing of 1.18009 arcsec. 04:06: OSU_monitor/N2403b: Collimation: Red Convergence reached for seeing of 0.853499 arcsec. Blue Convergence reached for seeing of 1.20582 arcsec. seeing decraded ~ 1.2 04:25: UM 2001sw273 Red Convergence reached for seeing of 0.957041 arcsec. Blue Convergence reached for seeing of 1.29210 arcsec. ~04:40: UM 1998kz12 Collimation: Red Convergence reached for seeing of 1.16119 arcsec. Blue Convergence reached for seeing of 1.36500 arcsec. 05:00 UM 2001sh142 Collimation: Red Convergence reached for seeing of 1.04298 arcsec. Blue Convergence reached for seeing of 1.33627 arcsec. 05:08: UM SA92 Collimation: Red Convergence reached for seeing of 1.03150 arcsec. Blue Convergence reached for seeing of 1.29680 arcsec. Clouds are moving in faster then we intisipated. They are starting to come in from the north but most of the sky is still clear. 05:29: ND_whim/fbqs0751phot collimation: Blue Convergence reached for seeing of 1.03365 arcsec. seeing red~0.9 blue~1.0 05:48: UM_Hildas/2004bm38_dec2011 collimation: Red Convergence reached for seeing of 0.861825 arcsec. Blue Convergence reached for seeing of 1.20917 arcsec. seeing: blue~1.0 red ~ 0.8 06:06: UM_Hildas/J0643_sloan collimation: Red Convergence reached for seeing of 0.668036 arcsec. Blue Convergence reached for seeing of 0.985138 arcsec. seeing red~0.7 blue ~0.9 Slight clouds moving in.. Also nothing in the queue airmass < 1.5 so we will revisit N2403 for free which was done earlier but at a pretty high airmass... Finally we need to re-co-point the telescope and the OSU monitoring is the only project with focus fields... 06:32: OSU_monitor/N2403free: collimation: Red Convergence reached for seeing of 0.729309 arcsec. Blue Convergence reached for seeing of 1.02921 arcsec. seeing ~ 1.1 06:50: UM_Hildas/1981eo29 collimation: Red Convergence reached for seeing of 0.669829 arcsec. Blue Convergence reached for seeing of 0.955021 arcsec. doubling exposure times becuase of cloud cover. seeing red~0.75 blue~1.0 07:10: UM_Hildas/RU152 collimation: Red Convergence reached for seeing of 0.750053 arcsec. Blue Convergence reached for seeing of 1.10008 arcsec. 07:26 OSU_monitor/N2903 collimation: Red Convergence reached for seeing of 0.948647 arcsec. Blue Convergence reached for seeing of 1.32026 arcsec. In the middle of the OB 2 of the red side exposures seemed to have not read out or saved properly. So at the end of the sequence down off/on other systems from gui. Since the OB exposes the same filter on the red side the entire observation, we then started the OB again and let it run the first two exposures after re-running dofpia and copointing at the focus field. 08:45 OSU_monitor/M81 collimation: Red Convergence reached for seeing of 0.817513 arcsec. Blue Convergence reached for seeing of 1.13834 arcsec. seeing red~1.0 blue~1.1 09:15 UM_Hildas/2004bm12 09:35: UM_Hildas/1981em20 Collimation may have been bad... There were just to few stars in of to the dofpia script to do well. Blue Convergence reached for seeing of 6.11027 arcsec. 09:43 OSU_monitor/M82 Collimation: Red Convergence reached for seeing of 0.681562 arcsec. Blue Convergence reached for seeing of 1.07918 arcsec. seeing red~ blue~0.9-1.0 ~10:05 OSU_monitor/N3077 Collimation: Red Convergence reached for seeing of 0.611604 arcsec.

Blue Convergence reached for seeing of 0.964461 arcsec. seeing red~0.65 blue~0.8 pretty good seeing 12:00 UM_Hildas/1981ec24_dec2011 Collimation: Red Convergence reached for seeing of 0.710725 arcsec.

Blue Convergence reached for seeing of 0.756895 arcsec. seeing ~0.75 Still pretty dim but lets hammer away at some flates. 200s g sloan z sloan flats up first (stopped after the first flat because the sky brightness was not rising as fast as I thought it was) last 2 exposures were saturated, dame sky snuck up quickly next g_sloan and i_sloan lets see if we can beat the rising sun with r_sloan I flats at 1s the last couple flats saturated but most looked ok
