Abstract:
We present the classification of 7 optical transients: 4 Type Ia SNe (z=0.043, 0.05, 0.08, 0.08) and 3 Type IIP SNe (z=0.03, 0.034, 0.04).

The Spectral Classification of Astronomical Transients (SCAT) survey (ATel #11444) presents the classification of 7 optical transients. We report optical spectroscopy (330-970nm, R~1200) taken with the University of Hawaii 88-inch (UH88) telescope using the SuperNova Integral Field Spectrograph (SNIFS). Transients were classified using the SuperNova IDentification code (SNID, Blondin & Tonry 2007, ApJ, 666, 1024). Additionally, we use photometry from the All-Sky Automated Survey for SuperNovae (ASAS-SN, Shappee et al. 2014, ApJ, 788, 48) to more accurately constrain the phase of each object. Redshifts given to 2 decimal places are derived supernova lines (via SNID), otherwise the redshifts are taken from NED or measured from narrow host galaxy emission lines.

TNS 2019jzt [ATLAS19odx] 00:54:32.221 +34:22:41.68 SN Ia-91T-like 0.08 SNID also provides several matches to pre-maximum SN Ia-norm templates, however, ATLAS first reported this object over two weeks ago. Considering the discovery date, we consider the post-max Ia-91T results more reasonable. 00:54:32.212 +34:22:41.83 SN Ia-91T-like 0.08
