S. Benetti and F. Bufano, Istituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova, on behalf of a larger collaboration, report that a spectrogram (range 380-810 nm, resolution 1.1 nm) of the possible supernova reported on CBET 2532, obtained on Nov. 5.08 UT by the Service Telescope Operator Team with the Ekar-Copernicus 1.82-m telescope (+ AFOSC), shows the new object to be a type-IIn supernova. The spectrum is dominated by a very strong H-alpha emission with a complex profile – the broad component of H-alpha having a FWHM of about 14000 km/s; H-beta is also present with a similar profile. He I emission lines are also clearly visible in the spectrum. Comparison of the observed spectrum with a library of supernova spectra via the "GELATO" code (Harutyunyan et al. 2008, A.Ap. 488, 383; available at website URL https://gelato.tng.iac.es/login.cgi) shows some resemblance to that of SN 1996al (Benetti et al., in preparation) around maximum light.
