The Spectral Classification of Astronomical Transients (SCAT) survey (ATel #11444) presents the classification of 10 optical transients. We report optical spectroscopy (330-970nm) taken with the University of Hawaii 88-inch (UH88) telescope using the SuperNova Integral Field Spectrograph (SNIFS). Transients were classified using the SuperNova IDentification code (SNID, Blondin & Tonry 2007, ApJ, 666, 1024).
