SN IIn

This spectrum is blue and featureless. Some narrow emission lines are the contamination of the host galaxy. A wider wing at the bottom of the Ha emission might due to the scattering effect. All of these might indicate this transient is a type II supernova at the relatively young phase. The best fit via Gelato is the SN IIn 1996al at t=23.4days after the peak but with low quality of fit.
