We report spectroscopic classification of objects from the Pan-STARRS Survey for Transients (PSST; Huber et al., ATel #7153; http://star.pst.qub.ac.uk/ps1threepi/ ). Observations were made with the SNIFS spectrograph on the UH 2.2m telescope (range 330-970nm, resolution R~1000) and the classification was done using SNID (Blondin and Tonry 2007, ApJ, 666, 1024) for supernova type.
