We conducted a spectroscopic observation of transient Gaia16amf at 2016-05-06T04:52:48 UT. This transient was observed by the Gaia Photometric Science survey on 2016-05-01T16:23:13 UT at position RA = 22:23:48.10, DEC = 41:33:45.30
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 SN2005am at +15 days with at SNID estimated red-shift of z=0.032. The transient is 0.108 arcmin from galaxy MCG +07-46-003, redshift z=0.031478 (source NED). The ejecta velocity estimated from the Si II 635.3nm absorption feature is ~10,400 km/s
