AndersonNoneSN Ia0.02072While looking at archival VIMOS data of SN host galaxies in the ESO archive, we found that one of the observations of NGC 0692 had a bright source that was not present in archival DSS images. We extracted a 2-arcsec aperture spectrum (4850-10000 A) at that location, and it clearly showed the main features of a type Ia supernovae at maximum light (S II W, Si II 5972 A, and Si II 6355 A). Host galaxy emission lines were superposed to the SN spectrum, and we measured a redshift of 0.02072 from H-alpha (in agreement with the galaxy redshift reported in NED, 0.02118). We estimate a Si II 6355 velocity of 12100 km/s. Comparing the SN spectrum with templates of several SNe of different types, GELATO (Harutyunyan et al., 2008, A&A, 488, 383) found the best fit to SNIa 2005am at +2.7 days past B-band maximum.2019TNSCR.158....1G
