Conditions good at start of night, only thin cloud on the horizon. Wind <10m/s humidity ~50%
seeing <1'' at the start of the night, ended with cloud
23.05 Started Sky flats gri
23.35 Standard l175
23.55 TCP17 classification in G11+G16 - G16 internal flat not worked, still on sky, the TO is reporting the problem. - looks very red, lots of absorption features and Halpha in emission
23.10 AS15qy - Type Ia ~5 days before peak - not in marshall yet, added from ATEL as good constraint on non detection and bright
23.25 PS15cgd - repeated from last night, observed for 1200s in good conditions - spectrum looks very similar. - can also get a spectrum of the other galaxy.
24.50 Switch to SOFI
01.00 image analysis
01.15 Standard Fiege100 seeing ~<1''
01.35 LSQ15adm JHK imaging seeing ~0.9'' in J,H band and seeing ~1.1'' in k band
02.50 AS15qc Telluric
03.00 AS15qc BG+RG
05.30 AS15qc Telluric
05.35 AS15qc imaging seeing ~1.4''
05.50 AS14Ko imaging seeing ~1.4''
06.05 changed to EFOSC
06.45 ASASN-14ha R band 18*100s imaging seeing <1.1'' thin clouds on horizon
07.35 PSNJ0205 45mins 1000s G11+G16 some thin cloud coming in during the G16 exposure
Cloud much thicker couldn't see any stars in acquisition images and clouds in red. Mirror closed. Waiting to see if improves.
Conditions stayed bad and had to close telescope
