Three bright transients, which are probable supernovae, have been discovered as part of 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). We will send all objects brighter than 18 mag as ATel alerts, while all other objects can be found on these webpages.

(1) NED reports that the probable host (8.64 arcsec away) is 2MASX J00275151-1128336.
(2) SDSS DR12 reports that the likely host (1.90 arcsec away) is SDSS J020020.04-020501.1 with photometric z=0.04061. At that redshift the absolute magnitude would be -18.0.
(3) NED reports that the likely host (21.47 arcsec away) is IC 0207 with spectroscopic z=0.016251. At that redshift the absolute magnitude would be -16.6.
