The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification of PSN J09100885+5003396 discovered by F. Ciabattari, E. Mazzoni and M. Rossi (Italian Supernovae Search Project ISSP) in UGC 4812.

Informations on these transients are available from the "Bright Supernova" website (http://www.rochesterastronomy.org/snimages/) and The Astronomer Telegram. The observations were performed with the Asiago 1.82 m Copernico Telescope (+AFOSC; range 340-820 nm; resolution 1.4 nm).

(1) Best match with the peculiar Type Ia SN 2009dc (a super-Chandrasekhar-mass SNe Ia; Taubenberger et al. 2011, MNRAS 412, 2735) about 10 days before B-band maximum light. The host galaxy redshift is deduced from the position of its emission lines.

Classification was done with GELATO (Harutyunyan et al. 2008, A&A, 488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024). The Asiago classification spectra are posted at the website http://sngroup.oapd.inaf.it.
