The transient, discovered by Fabio Briganti (Santa Croce sull'Arno - PI) in poor seeing condition, with the SC 11" f/6,3 of the Col Drusciè Observatory, in the cours of Italian Supernovae Search Project, needs a confirmation, because there is only a frame of the suspect. No known minor planets in the field at the time of discovery. Nothing is visible in red and blue plates of Palomar Sky Survey POSS2.
