We conducted a spectroscopic observation of transient ASASSN-16gv (AT 2016cyv) at 2016-07-07T03:18:09 UT.
This transient was observed by the All Sky Automated Survey for SuperNovae (ASAS-SN) survey on 2016-07-05T13:55:12 UT at position RA = 01:46:52.110, DEC = 33:23:21.57 as reported in ATel #9212.
A spectrum was obtained in the visible, 400-800nm, with resolution R~350, using the SPRAT spectrograph on the Liverpool Telescope located at Roque de los Muchachos.
Classification using SNID (Blondin and Tonry 2007, ApJ, 666, 1024) indicates it is a type Ia supernova. We find a close match with SN2003du at +2 days with a SNID estimated redshift of z=0.036.
The transient is 0.265 arcmin from galaxy CGCG 503-021, redshift z=0.037326 (source NED). The ejecta velocity estimated from the Si II 635.3nm absorption feature is 10,600 km/s.
