Observers: Noel Castro Segura & Miika Pursiainen Support: Charlotte Angus & Philip Wiseman TAT:Regis Cartier & Lluís Galbany Calibrations: EFOSC: biases dome flat fields arcs (evening and morning) Weather: Start: Some high clouds, seeing was ~1.0 for first hour but then quickly rose to 3 Middle: High clouds -> Restricted to only observe targets close to zenith, seeing varies between 1.5 and 3 End: Finally the clouds disappear and seeing stays moderate (1-1.5)Instrument - EFOSC UT Target Type Setup airmass Seeing notes ----------------------------------------------------------------------------------------- Image Focusing 00:15 VMA2 STD all 1.2 1.2 00:40 SN2018gjx Follow gr16 2.0 1.4 1 out of 2700s exposures finished.
