We report the following supernova classifications made from spectra obtained with the DEIMOS spectrograph on Keck II. Targets were supplied by the Pan-STARRS Survey for Transients (PSST). Information on all objects discovered by the Pan-STARRS Survey for Transients is available at http://star.pst.qub.ac.uk/ps1threepi/ (see Huber et al. ATel #7153). All observations were made on 2015 March 18 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | RA | Dec | Redshift | Type | Phase | Notes |
PS15ml | 15:27:17.60 | +37:50:50.3 | 0.033 | II | +5 d | |
PS15mt | 09:54:44.17 | +23:11:53.1 | 0.071 | Ia | -6 d | |
PS15oh | 13:10:03.03 | +10:04:28.9 | 0.05 | Ia | +12 d | a |
(a) Best matches are to SN 1991bg-like SNe, but there are also some good matches to normal SNe Ia.
