We report optical spectroscopy of 10 transients discovered by the OGLE-IV survey (L. Wyrzykowski et al. 2012, ATel #4495), CRTS (Drake et al. 2009, ApJ, 696, 870), and K. Hornoch (ATel #4723). The spectra (range 370-930nm; res. 0.7nm) were obtained UT Jan. 7-12 with WFCCD mounted on the du Pont 2.5-m telescope at Las Campanas Observatory. We used SNID (Blondin & Tonry 2007, ApJ, 1024, 666) to aid the identification, phase, and redshift determination of SNe.
