We report the spectroscopic classification of SN 2018ivc, discovered by the DLT40 survey in the nearby galaxy M77. The observation was performed with the Asiago 1.22 m Galileo Galilei Telescope equipped with the B&C spectrograph (range 330-790 nm; resolution 0.7 nm). Classification was done with GELATO (Harutyunyan et al. 2008, A&A, 488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024).

(1) The spectrum shows a blue featureless continuum, with superposed emission lines of the host galaxy, including Halpha, Hbeta, [O III], [S II]. Although no classical SN feature is evident yet, this spectrum is consistent with that of a young core-collapse SN, most likely a type II event soon after the explosion. This agrees with the TNS Classification Report No 3087. The redshift of M77 is from Huchra et al. 1999, ApJS, 121, 287.
