Six bright transients, which are possible supernovae or high amplitude galactic variables, 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 (3.0 arcsec away) is GALEXASC J012224.56-134733.9. No redshift is recorded. This object was classified by PESSTO on 2015-11-07 as a SNIa. See ATel #8255.
(2) NED reports that the likely host is 2MASX J03080479-0314543 with spectroscopic redshift z=0.029784. The object lies 0.14 arcsec from the galaxy core. At this redshift the absolute magnitude at discovery is ~ -18.27.
(3) The object is at galactic latitude b=9.44 and appears coincident with a source in the PS1 z-band reference stack. It is likely to be a CV or high amplitude galactic variable.
(4) The object is at galactic latitude b=-11.06 and appears to be coincident with a faint source in the PS1 i-band reference stack. It is likely to be a galactic variable.
(5) SDSS DR12 reports that the likely host (0.26 arcsec away) is SDSS J222428.42+323932.2.
(6) NED reports that the likely host (15.46 arcsec away) is SDSS J215935.26+120328.1 with spectroscopic redshift z=0.045330. At this redshift the absolute magnitude at discovery is ~ -19.30.
