Andrew Howell, Curtis McCully, Stefano ValentiGlobal SN ProjectSN Ia0.023771Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find several good fits to normal Type Ia SNe around a week before maximum light at the redshift of the proposed host galaxy (z=0.024; Jones et al. 2009, "The 6dF Galaxy Survey Data Release 3," via NED). The narrow H_alpha line is likely to be host contamination.

Lopez-Sanchez (AAO, Maquarie U.), Yago Ascasibar (UAM), Kristin Fiegert (AAO)SN Ia0.0191We report the spectroscopic classification of SN 2018brz (RA=08:33:22.27, DEC=-76:37:39.8) in an anonymous host galaxy. The candidate was discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN: Shappee et al. 2014) on UT 2018-05-15 at ~16.5 mag. Observations were performed on the 4m Anglo-Australian Telescope at Siding Spring Observatory on 2018 May 19 9:15 UT, using Koala+AAOmega and Grisms 580V+1000R (3500-6000A and 6300-7300A). Classification was done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). The spectrum shows the typical "W" SII absorption (5454,5640A), and MgII, and FeII features characteristic of type Ia supernovae. SNID gives a reasonable fit to all its main spectral features with the pre-peak spectrum of SN 1999aa placed roughly at z ~ 0.019. Velocities measured at the bottom of both SII absorptions are consistent with -9,500 km/s.
