Abstract:
We report the spectroscopic classification of SN 2019nud as type II SN close to explosion

The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841), reports the following supernova classification.

The target was supplied by the Zwicky Transient Facility (ZTF, see Atel #11266) via ALeRCE (http://alerce.science/). 

The observation was performed with the Asiago 1.82m Copernico Telescope (+AFOSC; range 340-820 nm; resolution 1.4 nm).

The classification was performed using the GELATO (Harutyunyan et al. 2008, A&A, 488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024) tools. The Asiago classification spectrum is posted at the website http://sngroup.oapd.inaf.it.

A broad (about 13000 km/s) Halpha emission is also clearly detected. 21:38:33.620 +44:09:32.61 SN II 0.038974
