Observer: Francesco Taddia TAT on duty: Janet Chen, Lluís Galbany Support team: Cristina Barbarino, Anders Nyholm, Emir Karamehmetoglu, Jesper Sollerman Daytime calibrations: PESSTO_bias, PESSTO_calib (only arcs) --please consider only the calibrations taken after the night due to some instrument problems before the night Twilight calibrations: BgVri sky flats taken in the morning seeing 0.85" at 04:19, it jumped to higher values before that. 00:16 image analysis, problems with the instrument, the images do no show signal from any sources, like there was an interruption of the optical path. A technician went to the NTT to check. The problem was solved, we started observing the first target with about 30 min delay. UT/Target/RA/DEC/time spent(min)/slit/grism or filter /description 00:55 SN2016gkg 01:34:14.46 -29:26:25.0 45 1 gr16 FOLLOW-UP. Good spectrum. 01:39 AT2016hmq 04:25:04.91 -07:33:56.2 52 1 gr13 FOLLOW-UP. It appeared fainter than last time we observed it, the spectrum shows Halpha in emission but not much else. 02:32 OGLE17abx Attempted, despite 40 sec acquisition image it looked very faint, therefore we aborted. 02:37 SN2016aqf 05:46:23.91 -52:05:18.8 52 1 gr13 FOLLOW-UP. Clear nebular lines in the spectrum. 03:32 AT2016jbu 07:36:25.96 -69:32:55.2 30 1 gr11+gr16 FOLLOW-UP.
