The Asiago Transient Classification Program (Tomasella et
al. 2014, AN, 335, 841) reports the spectroscopic classification of
PSN J21534826+1003249 in MCG+2-55-26.
Information on this transient is also available from the "Bright
Supernova" website (http://www.rochesterastronomy.org/snimages/) and
the CBAT Transient Object Followup Reports (http://www.cbat.eps.harvard.edu/index.html). The observations were performed with the Asiago 1.82 m Copernico Telescope (+AFOSC; range 340-820 nm; resolution 1.4 nm).

1) The redshift of the host galaxy (MCG+2-55-26) is from Huchra et al 2012 ApJS 199,26 via NED. The expansion velocity deduced from the Si II 635.5 nm absorption is about 6500 km/s.
Classifications were done with GELATO (Harutyunyan et al. 2008,
A&A, 488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024). The
