Observers: Noel Castro Segura & Miika Pursiainen Support: Charlotte Angus & Philip Wiseman TAT:Regis Cartier & Lluís Galbany Calibrations: EFOSC: biases arcs (begin and end of EFOSC observations) SOFI: Flat JHK arcsSpec flats (morning) Issues: -NTT had minor issues during the daytime so not all calibrations could be performed during the day time and were pushed into morning -During the first science exposure SOFI developed a CCD fault. However, this was not the standard one affecting only one quadrant, but affected all four quadrants instead.Weather: Start: Almost ideal, seeing 1-1.5", humidity 25%, wind <5m/s Middle: Seeing 1-1.5" End: Seeing ~1 Instrument - SOFI UT Target Type Setup airmass Seeing notes ----------------------------------------------------------------------------------------- 00:35 SN2018ilu Follow JHK 1.3 1.3 First attempt had to be aborted due to SOFI CCD fault developed 1/3 into the OB 01:20 SN2018ilu Follow JHK
