TNS Classification Report No. 311 [ 2016TNSCR.518....1H ]
Date Received (UTC): 2016-08-03 20:15:30 Sender: Isaac Shivvers

G. Halevi, H. Yuk, I. Shivvers, A. V. Filippenko report/s a classification of object: SN 2016ehy
Type: SN Ia
Remarks: We report that a CCD spectrum (range 350-1050 nm) of AT2016ehy was obtained on Aug. 02.3 UT with the 3-m Shane reflector (+ Kast spectrograph) at Lick Observatory. The object was classified via cross-correlation with a library of supernova spectra using the "SuperNova IDentification" code (SNID; Blondin & Tonry 2007, Ap.J. 666, 1024) including the updated templates of Silverman et al. (2012 MNRAS, 425, 1789) and Liu & Modjaz (2014 arXiv:1405.1437). We find that AT2016ehy is a Type Ia supernova approximately 20 days post maximum brightness. SNID identifies similarities to SN 1999aa-like events (SN 1999aa itself and SN 2008ds) as well as similarities to the spectra of several normal SNe Ia. See Astronomer's Telegram #9309.
