Following the posting on the Central Bureau's Transient Object Confirmation Page about a possible Nova in Sco (TOCP Designation: PNV J17032620-3504140) we performed some follow-up of this object remotely through a 0.50-m f/6.8 astrograph + CCD + f/4.5 focal reducer) of iTelescope network (MPC Code  Q62 - Siding Spring).

On our images taken on February 13.7, 2015 we can confirm the presence of an optical counterpart with R-CCD magnitude 8.6 at coordinates:

R.A. = 17 03 26.19, Decl.= -35 04 18.1

(equinox 2000.0; UCAC3 catalogue reference stars).
