Two 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 likely host (8.56 arcsec away) is UGC 06520 with spectroscopic z=0.012255. At that redshift, the object would have an absolute magnitude of ~ -16.3.
(2) SDSS DR12 reports that the likely host (0.47 arcsec away) is SDSS J153131.39+330604.3 with photometric z ~ 0.12. PS1 observed the object to brighten by 0.45 magnitudes on 20150727.
