Following the posting on the Central Bureau's Transient Object Confirmation Page about a possible Nova in Oph (TOCP Designation: J17395600-2447420) we performed some follow-up of this object remotely through the 0.43-m f/6.8 astrograph + CCD of ITelescope network (MPC Code - H06). On our images taken on May 20.3, 2012 we can confirm the presence of an optical counterpart with unfiltered CCD magnitude 9.5 at coordinates: R.A. = 17 39 57.00, Decl.= -24 47 07.3 (equinox 2000.0; CMC-14 catalogue reference stars).
