The intermediate Palomar Transient Factory (ATel #4807) reports the classification of the SN2016csv, discovered by ATLAS survey (see Tonry et al. ATel #8680) as ATLAS16bel. This object was also independently discovered by the Gaia ESA survey as Gaia16asg. The observations were performed with the 60 inches optical telescope at out Palomar (P60) and the Spectral Energy Distribution Machine (SEDM) (http://www.astro.caltech.edu/sedm/, range 350-950nm, spectral resolution R~100) on 2016-07-05 07:15:11.6 UT.

(1) Best fit template from SNID is SN1999em. Expansion velocities of ~11000 km/s (from Halpha absorption).
Classifications were performed using SNID (Blondin and Tonry 2007, ApJ, 666, 1024).
