Two transients 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) The object is coincident with faint source in the PS1 reference stack and SDSS DR12 at i=21.3. It is either a SN in a faint host or a high amplitude galactic variable.
(2) This is 4.12 arcsec from the core of UGC 01634, which is a face-on spiral at z=0.016605 (mu=34.1; D = 67 Mpc). This implies an absolute magnitude of M_r = -14.1 (with foreground extinction of A_r = 0.35) if associated with UGC 01634. This could be an intrinsically faint transient in this galaxy or quite young, old, or reddened supernova. Spectroscopic classification is encouraged.
