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 4134 (z = 0.012739). The new object, dubbed (by the IAU) PSN J12091154+2910209, is located at (J2000.0) coordinates RA = 12:09:11.54, Dec = +29:10:20.9. Following discovery in an unfiltered image obtained at 09:12 UT on 2014 April 24, 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 = 17.6 mag at this time. A previous KAIT image taken on April 16 did not detect the object with limiting mag ~18.1. Spectroscopic observations are encouraged. A finding chart is available at the following website: http://astro.berkeley.edu/~zwk/findingchart/PSN_J12091154+29102086.jpg
