SN 2013gc is the first case of a type IId supernova with detections of outburst episodes before the explosion. During these outbursts the progenitor star expelled a circumstellar shell, which later interacted with the SN ejecta. The spectra show multiple components in emission, with a narrow P Cygni profile. The spectra and the light curve were compared with those of similar objects. The talk will be a description of the study done on this interesting object.
