MDM Spectroscopic Classifications of PSST Transients

We obtained optical spectra (range 4000-9000 Angstroms) of three transients with faint or undetected host galaxies reported by the Pan-STARRS Survey for Transients (PSST; Huber et al., ATel #7153). Observations were carried out 2016 May 8-9 UT using the 2.4 m Hiltner Telescope and OSMOS at MDM Observatory. Classifications were performed using the SuperNova IDentification code (SNID; Blondin & Tonry 2007, ApJ, 666, 1024) with the BSNIP templates of Silverman et al. (2012, MNRAS, 425, 1789) and are reported below:

(1) The age is near maximum light and the best-fit SNID template is SN 1989B at an age of -0.5 d. (2) The best-fit comparison is SN 1993J at an age of +20 days after (second) maximum light at a redshift of 0.047. (3) Approximate age is +9 days after maximum light. The best match found by SNID is SN 1995D at an age of +10 days.
