LBT OSU/RC Partner OBserving Notes Date: 2015 January 20 UTC (Night 3 of 9) Observers: Paul Martini, Suk Sien Tie (OSU), Jake Turner (UVa) Support Astronomer: Olga Kuhn (remote) Telescope Operator: David Gonzalez-Huerta SUMMARY: Thin clouds at start and about 1.2" seeing. Appeared to clear completely after a couple hours, and seeing stayed at 0.9-1" for the rest of the night. Completed OSU_ASASSN SN14dc, 14li, OSU_MClusters PraA and PraB ND_void, ND_LRGCGM, ND_SN14ad, ND_4013disk Observing Notes: All times are UTC unless otherwise noted 01:14 Pointing check 01:29 OSU_z6q 3 acq A few clouds 01:39 First image: sky still too bright 01:53 OSU_z6q 3 acq on target 01:56 OSU_z6q 3_... observation seeing: 1.3 light clouds Clouds right where we are looking Diff image is barely detected, so calling this a nondetection 02:42 g191b2b std star acq 02:50 g191b2b std star observation 03:10 VM_Vshift acq 03:14 Error: no guide star checking pointing 03:21 VM_Vshift acq retry col on different star 03:27 VM_Vshift aborted Too faint guiding star 03:28 OSU_ASASSN N14dc acq We centered the slit in the middle of the ccd, had to fix with a offset We then centered the galaxy insead of the SN Something with the pointing wasn't right and we did acq again 03:57 OSU_ASASSN N14dc acq again 04:03 OSU_ASASSN N14dc obs 0.89 seeing clear 04:42 OSU_MClusters PraA acq Took a while to figure out best pa to fit both targets on slit 05:15 OSU_MClusters PraA obs Seeing 1.2 Clear sky 05:40 OSU_MClusters PraB acq 05:58 OSU_MClusters PraB obs Spent too much time on aligning, so just observing one of two targets Seeing 0.96, clear sky 06:16 Redo OSU_MClusters PraB obs (error on object timing out after 60 s) Seems like slit still managed to capture the second object, but probably lower snr than desired. 06:34 ND_void acq 06:46 ND_void obs Seeing 1.1, clear sky 07:27 ND_LRGCGM acq 07:35 ND_LRGCGM obs 08:29 ND n4013disk acq 08:45 ND_n4013disk obs Seeing 1.1, clear 09:24 OSU_ASASSN SN14lp acq 09:45 Abort OSU_ASASSN SN14lp obs due to wrong SN coordinates 09:49 UM_Vshift KISS acq Telescope preset error because script didn't have guide star name 09:57 UM_Vshift KISS re-acq after added dummy name for guide star 10:10 UM_VShift KISS obs Seeing 0.87, clear 10:48 ND_sn14ad acq Target very close to another object; had a hard time deciding which one is the real source. Eventually settled on the brighter one. 11:12 ND_sn14ad obs 12:14 OSU_ASSASN14li acq 12:24 OSU_ASSASN14li obs Seeing 1.2 Clear 13:01 OSU_ASSASN14ms acq HA1 We are near Twilight, so not doing 13:07 Feige 34 cal acq 13:11 Feige34 cal obs (dual grating and dual prism) Seeing 1, clear skies at morning twilight
