Three 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) Also known as PS16je. NED reports that the likely host (1.32" away) is SDSS J091640.82+221752.2, with spectroscopic z=0.050376. The object was originally discovered at magnitude w=19.2, but photometry obtained on 2016-01-18 indicates that it brightened to r=17.95. At the host redshift the absolute magnitude is -18.75.
(2) Also known as PS16fw. SDSS DR12 reports that the likely host (4.2" away) is SDSS J074131.85+363910.2, with photometric z=0.060. The object was originally discovered at magnitude w=19.74, but photometry obtained on 2016-01-16 indicates that brightened to r=17.7.
(3) Also known as PS16iu. NED reports that the likely host (8.58" away) is 2MASXi J0838508-002000. SDSS DR12 gives the potential host (also known as SDSS J083850.91-002001.4) a photometric z=0.050.
