We report the discovery, with the 0.76-m Katzman Automatic Imaging Telescope (KAIT) at Lick Observatory, of a possible new supernova in the nearby galaxy UGC 2789. The new object, dubbed PSN J03361605+6734157 (by the IAU), is located at (J2000.0) coordinates RA = 03:36:16.05, Dec = +67:34:15.7. Following discovery in an unfiltered image obtained at 10:13 UT on 2013 Oct. 11, KAIT autonomously began a sequence of triggered follow-up observations in the U, R, I, and clear (roughly R) filters beginning only 5 minutes later. Using stars from the USNO-B1 catalog for reference, we measure R = 18.2 mag at this time. Previous KAIT imaging on 2013 Oct. 09 revealed no emission at this location to a limit of R~18.8 mag, indicating the object might be a very young SN. Further observations are encouraged.
