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 NGC 4096 (z=0.00183). The new object, dubbed PSN J12060299+4729335 (by the IAU), is located at (J2000.0) coordinates RA = 12:06:02.99, Dec = +47:29:33.5. Following discovery in an unfiltered image obtained at 05:59 UT on 2014 May 31, 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~18.2 mag at this time. The target was also detected on May 27 with R~18.2 and was marginally detected on May 21 with R~18.5. Earlier image on 2014 May 13 revealed no emission at this location to a limit of R~18.6 mag.
