The Caltech Time Domain Astronomy group reports the classification of Gaia16atw and Gaia16aui, discovered by the Gaia ESA survey. The observations were performed with the Spectral Energy Distribution Machine (SEDM)(http://www.astro.caltech.edu/sedm/, range 350-950nm, spectral resolution R~100) on Palomar 60-inch (P60) telescope.

(1) Best fit template from SNID is SN1996L.
(2) Best fit template from SNID is the peculiar SN Ia - SN200cx.
Classifications were performed using SNID (Blondin and Tonry 2007, ApJ, 666, 1024).
