A bright transient, which is a probable supernova, 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) NED reports that the likely host (10.4 arcsec) away is KUG 0308+010 with a spectroscopic redshift of 0.027. At this redshift the absolute magnitude at discovery is -17.46. Non-detections constrain the explosion epoch to no more than 9 days before discovery, consistent with the estimated absolute magnitude and suggesting the transient may still be rising.
