Comments: Used the 1.5"slit for all the observations as the seeing was very bad, except the first one No Image analysis was done due to the bad conditions
AT2019tpl was not seen in the acquisition image with 1 min exposure (maybe due to bad seeing?) so it was not observed EFOSC calibrations were done at the end of the night
