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 MCG-01-10-039 (z=0.013504 ). The new object, dubbed PSN J03490564-0303283 (by the IAU), is located at (J2000.0) coordinates RA = 03:49:05.64, Dec = -03:03:28.3. Following discovery in an unfiltered image obtained at 08:27 UT on 2013 Nov. 09, KAIT autonomously began a sequence of triggered follow-up observations in the U, B, V, R, I, and clear (roughly R) filters beginning only 5 minutes later. Using stars from the USNO-B1 catalog for reference, we measure R = 16.9 mag at this time. Previous KAIT imaging on 2013 Nov. 05 revealed no emission at this location to a limit of R~18.5 mag, indicating the object might be a young SN. An image was also taken on Nov. 07, but was unfortunately useless due to cloudy weather. Further observations are encouraged.
