A. Klotz on behalf of the TAROT Collaboration reports the discovery of an apparent supernova (mag about 15.6 +/- 0.4) on 2012 Oct. 27.05 using public images of the 0.25m robotic telescope TAROT La Silla observatory, Chile. SN is located at about R.A. = 03h33m36.1s, Decl. = -36o07'34" (equinox J2000.0), which is 3" W and 52" N from the nucleus of NGC 1365. The supernova does not appear in an image taken 2012 Oct. 24.05 (limiting mag 15.8) neither in an image taken 2012 Oct. 19.37 (limiting mag 19.2). The candidate appears in the two 30s unfiltered frames of NGC 1365 taken sequentially. It remains a doubt on the reality of the object because it can be a CCD artifact. However, this kind of artifact is not usual in the TAROT images. Additional informations http://cador.obs-hp.fr/sn_tarot/PSN_J03333599-3607377

Emmanuel Conseil (amateur of astronomy - France) reports the confirmation of the presence of a new stellar object at the position of the PSN J03333599-3607377 described in the TOCP page. Images were obtained with the 0.5m Slooh Space Camera robotic telescope (Canaria island). Magnitude 16.0U at the date 2012 Oct. 27.125 UT.

TAROT observations of the supernova in NGC 1365 are continuing. At the date 2012 Oct. 29.22 magnitudes are 14.69B, 14.27V, 14.02R. At the date 2012 Oct. 30.22 magnitudes are 13.96B, 13.78V, 13.64R. These magnitudes are calibrated using 16 Loneos stars in the nearby field of NGC 1316.

Jonathan Normand (amateur of astronomy - France) reports a limiting magnitude from a stack of images taken with the 60 cm telescope at the observatoire des Makes, Reunion Island (Pacific Ocean). At the date 2012 Oct 24.02 the supernova was fainter than magnitude 19.3 in the R band.
