A bright transient, which is a possible supernova or high amplitude galactic variable, has 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 transient is coincident with a faint source. It is catalogued in Sloan as SDSS J234404.66+440034.2, r=23.2 +/-0.25, and appears point like in PS1 r-band reference stack. At this magnitude, star-galaxy separation in both SDSS and PS1 is uncertain. But a point source is more likely, and short time-scale structure in the PS1 r-band lightcurve points toward a galactic source, probably a CV.
