SUPERNOVA 2014Y = PSN J07233339+5426302
     L. Tomasella, S. Benetti, E. Cappellaro, A. Pastorello, P. Ochner, N.
Elias-Rosa, and M. Turatto, Osservatorio Astronomico di Padova, Istituto
Nazionale di Astrofisica, report that an optical spectrogram (range 340-820
nm; resolution 1.3 nm) of PSN J07233339+5426302 = SN 2014Y (cf. CBET 3821),
obtained on Mar. 8.95 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC),
shows it to be a type-IIn supernova.  Adopting for the presumed host galaxy
a redshift z = 0.039 from the position of H_alpha, a good match is found with
several type-IIn supernovae soon after explosion.  A good fit is also found
with the type-Ia/IIn supernova 2005gj (Aldering et al. 2006, Ap.J. 650, 510),
especially if one allows for some reddening on the order of E(B-V) around 0.5.
The Asiago classification spectra are posted at http://sngroup.oapd.inaf.it;
classification was made via GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383)
and SNID (Blondin and Tonry 2007, Ap.J. 666, 1024).
