16432018-01-16 12:41:15msiebertM. R. Siebert, G. Dimitriadis, R. J. Foley (UCSC)NoneSN Ia0.0052741The spectrum indicates that SN 2018gv is a very young, normal Type Ia supernova. Using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024), we find a good match to several Type Ia SNe 10-15 days before maximum brightness. We note that the small number of SNe Ia observed at very early phases often results in a bias to later phases. The SN was discovered at 16.5 mag, which assuming a distance modulus of 31.1 mag for the host galaxy NGC 2525 (Tully et al., 2013, AJ, 146, 86T), corresponds to an absolute magnitude of -14.8 -- or at least 4 mag below peak brightness. This further indicates that the SN is particularly young. If the SN has minimal host reddening, it will peak at V ~ 12 mag. We measure an Si II 6355 velocity of -16,800 km/s. Similarly, we measure a C II 6580 velocity of -15,300 km/s. We detect narrow Ca H&K absorption at the host-galaxy redshift, but do not detect narrow Na D.

Andrew Howell, Stefano ValentiLCOGT SN-KPLBV0.0011LCOGT SN-KPThe spectrum shows a H-alpha emission at the redshift of the proposed host galaxy (z=0.001; Garrido, Marcelin, & Amram 2004, MNRAS, 349, 225; via NED) with a width corresponding to ~950 km/s (marginally resolved by the spectrograph) on top of the somewhat blue continuum of the host (SDSS DR13). Given that the discovery magnitude was 18.5 mag, corresponding to an absolute magnitude of ~-11 mag (Tully 1988, Nearby Galaxy Catalog; Sharina, Karachentsev, & Tikhonov 1999, AstL, 25, 322; via NED), we conclude that the transient is likely an extragalactic LBV outburst (i.e. a supernova impostor).
