Mattila, University of Turku; on behalf of a larger collaboration, report that low-S/N spectrograms of PSN J03383439+2232595 = SN 2011jc, obtained on Dec. 16.01 and 18.92 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC; range 350-820 nm; resolution 2.4 nm), on Dec. 19.0 with the Nordic Optical Telescope (+ ALFOSC; range 320-910 nm; resolution 1.6 nm), and on Dec. 19.05 with the William Herschel Telescope (+ ISIS; range 300-975 nm; resolution 1.2 nm) show that 2011jc is a type-IIn supernova. The best fits to these spectra found by GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383; available at URL https://gelato.tng.iac.es/login.cgi) suggest that 2011jc is similar to SN 2005gj (comparison spectra are from Padova-Asiago Supernova Archive) a few days after explosion, if a redshift of 0.087 is assumed for the host galaxy.
