Seven bright 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) NED reports that the likely host (1.32" away) is GALEXASC J152022.83+685119.8. Subsequent i-band photometry acquired 28 days after discovery shows that the object faded by ~ 0.2 mags. No photometry was acquired during the intervening period, but difference photometry extracted from ATLAS implies activity before the PS1 discovery. The ATLAS lightcurve is roughly flat at o ~ 17.5 mags between 58 and 31 days before PS1 discovery possibly indicating a type IIP SN.
(2) The object is at galactic latitude b=11.31 and is coincident with SDSS J180226.28+005537.6. It is likely to be a CV or high amplitude galactic variable.
(3) The object is at galactic latitude b=-10.69 and appears coincident with a faint source in the PS1 z-band reference stack. It is likely to be a CV or high amplitude galactic variable.
(4) NED reports that the likely host (3.16" away) is ESO 567- G 025 with spectroscopic redshift z=0.029921. At this redshift, the absolute magnitude at discovery is ~ -18.6.
(5) NED reports that the likely host (1.03" away) is SDSS J090540.16+590234.2 with spectroscopic redshift z=0.045027. At this redshift, the absolute magnitude at discovery is ~ -18.9.
(6) NED reports that the likely host (4.38" away) is GALEXASC J130500.27-111523.9 with spectroscopic redshift z=0.044447. At this redshift, the absolute magnitude at discovery is ~ -18.6.
(7) NED reports that the likely host (3.42" away) is 2MASX J10233359+6439588 with spectroscopic redshift z=0.040301. At this redshift, the absolute magnitude at discovery is ~ -18.2.
