Additional information on ATel #12313.
The discovery of the supernova candidate ASASSN-18nt (AT 2018ctv) was reported by Ping Chen et al (ATel #11762). Subo Dong et al. (ATel #11763) identified the type, phase, and redshift of the SN using the Low Dispersion Survey Spectrograph 3 (LDSS3) mounted on the 6.5m Magellan Clay telescope and concluded that the spectrum of SN2018ctv matches with SN 1991bg-like SNe Ia near peak and the SN redshift is consistent with that of the Abell 0194 cluster of galaxies (z=0.018). The difference of the INT WFC magnitudes of SN2018ctv with the measurements close to the peak of the light curve are also broadly consistent with the light curves of SN 1991bg-like SNe.
Based on observations made with the Isaac Newton Telescope operated on the island of La Palma by the Isaac Newton Group of Telescopes in the Observatorio del Roque de los Muchachos.
