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 2196 (z=0.00775). The new object, dubbed PSN J06120295-2149353 (by the IAU), is located at (J2000.0) coordinates RA = 06:12:02.95, Dec = -21:49:35.3. Following discovery in an unfiltered image obtained at 06:39 UT on 2014 Jan. 20, 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 = 18.0 mag at this time. Previous KAIT imaging on 2014 Jan. 17 revealed no emission at this location to a limit of R~18.5 mag, indicating the object might be a young SN. Spectroscopic observations are encouraged.
