A. Klotz (IRAP France) used the robotic TAROT telescope at la Silla, Chile. Refined photometry has been performed using an archive image without the supernova as a substractive mask. Images are R filtered. The star NOMAD-1 0283-0902057 R=14.07 is choosen as the photometric calibrator. Date mag 2012 06 08.34 >19.0R 2012 06 20.36 19.6R 2012 06 26.34 17.9R 2012 07 02.16 17.2R 2012 07 08.15 17.3R Using NED data for extinction and luminosity distance, we deduce an absolute R magnitude -18.3 at the date 2012 Jul. 02.16.
