Two bright transients, which are possible 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 (8.96 arcsecs away) is UGC 11445 with spectroscopic redshift 0.023783. At that redshift, the object would have an absolute magnitude of ~ -17.05. PS1 photometry obtained two days after discovery indicates the object is fading.
(2) The transient has no clear host detected, but may be associated with the galaxy SDSS J230602.44+333617.7 offset by 16.19 arcsecs. This galaxy has a photometric redshift of ~ 0.028.
