Night Report 2017-09-27
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
~01:50 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
