Observers: Kris Rybicki, Simon Hodgkin TAT: Regis Cartier, Janet Chen Support team: Morgan Fraser, Emma Callis Calibrations: biases, dome arcs+flats - apparently some problem with flats Conditions: Thick cloud, closed at sunset. 00:45 Opened! (still somewhat cloudy) 01:17 Seeing 0.9 arcsec ~01:20 Refocussed ~01:50 Refocussed (Guide star looked like a comet)` ~03:35 Closed for Cloud 05:00 Reopening after cloud - but an issue with an interlock (dome/instrument rotation?) has forced the TO to go up to the telescope to clear it. 06:05 got on telluric STD. It's definitely clearer - though not clear - but target is hard to identify. 06:35 Swapped back to EFOSC Then CLOSED for good, almost immediately UT Target Type Comment ============================================================================================== 12:55 EG131 STD Still some cloud 01:34 AT2017gwx Classify Looks positively murky. Spectrum blue, Z=0 Balmer series in absorption, Halpha in emission. 01:55 AT2017gwt Classify SN Ia (norm, close to max, Z~0.06) 02:15 AT2017gwy Classify SN Ia (also close to max) 02:30 ATLAS17lau Classify Aimed for the galaxy nucleus in hope, but nothing obvious there: just a faint galaxy spectrum 02:50 Feige 110 03:22 AT2017gww Classify Observed in thickening cloud with GR13. Looks like a young SN type II 06:05 HIP024337_A Telluric 06:15 N113-YSO04_A Acquisition Target not obvious from finding chart 06:53 Feige 110 Aborted |
