Observers: Kevin Croxall, Michael Fausnaugh SA: Dave T. TO: Steve A. Summary: Light to moderate cirrus throughout the entire night. Seeing started off at ~1.1 arcsec, then jumped to ~1.3 arcsec, and then 1.5-1.8" Started with LBC, clouds came in thicker so moved to MODS. Dome was shut for a bit then opened to variable seeing and clouds. obtained data on OSU_Monitor/N925 and OSU_LensedQSOs/he0435 however, these are likely not science quality due to heavier clouds. They have not been removed from the queue. Completed programs in MODS: OSU_RV/m35w_15006, OSU_ASN13db, OSU_ETG/ngc2768, OSU_RV/m35_w38028 Completed programs in LBC: OSU_Monitor/N6946 ********************************************************** PEPSI: working at sunset and through twilight. During re-configuration to LBC Rick ran some engineering tests to looking into MODS issues with the IMCS LBC: Lovely weather, clear sky. 01:30 Send pre-set to OSU_Monitor/N6946 focus field 01:35 Start collimation with dofpia. not running mirror ventilation 01:48 Start observation 02:04 images elongated. re-running dofpia. LBC crashed. 02:11 re-started science exposures ~1.3" seeing 02:44 some moderate cirrus rolling through last exposure 02:47 LBC crash after readout 02:51 dofpia OSU_Monitor/N925 02:56 starting observation. moderate clouds present. 03:09 heavier clouds, not science grade images. 03:30 thicker clouds. ~5 mag of extinction. Aborted imaging. ***** 03:35 START SWITCHING TO MODS1 ************* 03:35 closing dome while re-configuring to MODS and waiting on clouds. 05:15 clouds have thinned some. Re-opening 05:21 starting acquisiton for OSU_LensedQSOs/he0435 seeing ~1.7 05:25 guide star too close to the edge, used modsView to select a new guide. 14.8mag guide star nigh unto too faint MODS1 still stepping slit. image naming hanging. Got Rick on the phone to de-bug issue 06:13 started observation after manual slit imaging. 06:56 starting acquisition on OSU_RV/m35w_15006 07:33 starting acq on ASN13db 07:43 started obs, uped integration to 600s per image due to slit looses and clouds. Seeing ~1.4" took Ne lamp in red and Ar lamp in blue following the observation mods1r.20131203.0028 & 29 were label as ASN13db but were the Ne lamp 08:56 started obs on OSU_ETG/ngc2768 seeing ~1.8" 09:18 seeing ~1.5" lines evident in spectrum. 09:38 last 2 images in ngc2768 hit by worse clouds. Not sure how useful they are. 09:44 start acq on OSU_RV/m35_w38028 13.82 mag guide star not bright enough. 09:59 closed due to clouds. 10h05 taking MODS calibrations 11:44 reopened as clouds have cleared somewhat. Wind a bit stronger. 11:45 start acq on OSU_RV/m35_w38028, seeing ~1.8" 11:59 start obs 12:24 start acq Feige 34
