From images taken from 2013 May 02.22 to 2013 May 26.22 with the TAROT 25 cm telescope (TAROT La Silla, Chile) E. Conseil reports the discovery of a supernova candidate located at R.A. = 13h50m52.85s, Decl. = -30o17'09.7" (equinox 2000.0), which is offset of 12" W and 12" N from the nucleus of ESO 445-G056. The image was R filtered and the magnitude ares: 2013 May 02.22 mag=18.4R. 2013 May 05.26 mag=17.2R. 2013 May 08.27 mag=16.5R. 2013 May 14.25 mag=15.7R. 2013 May 17.00 mag=16.1R. 2013 May 20.23 mag=16.2R. 2013 May 26.22 mag=16.3R. The light curve is compatible with a SNIa supernova with a maximum of brightness happened on 2013 May 15 at magnitude R=16.
