We report the discovery, with the Hubble Space Telescope Advanced Camera for Surveys (HST/ACS), of a probable supernova in the nearby galaxy Mrk 477 (z=0.037726). This object is located at 2.4" from the nucleus of Mrk 477, along PA = 140 degrees, at (J2000.0) coordinates RA = 14:40:38.30, Dec = +53:30:13.8. The supernova was discovered on narrow band images, centered at rest frame wavelengths 500 nm and 550 nm, on 2015 July 08.31 UT. We measured V~16.9 mag in both filters, corresponding to M_V ~ -19.1 mag (absolute V magnitude). Previous images of this galaxy, obtained on 2013 November 24, do not show this target.
