Following the posting on the Central Bureau's Transient Object Confirmation Page about a possible Nova in Cen (TOCP Designation: PNV J13544700-5909080) we performed some follow-up of this object remotely through the 0.50-m f/6.8 astrograph + CCD + focal reducer of iTelescope network (MPC Code Q62 - Siding Spring, AU).On our images taken on December 03.68, 2013 we can confirm the presence of an optical counterpart with unfiltered CCD magnitude ~ 5.0 at coordinates:R.A. = 13 54 45.22, Decl.= -59 09 04.5 (equinox 2000.0; UCAC-3 catalogue reference stars).According to Vizier the nearest star (located at 1.538 arcsecond from the transient) to this position in the USNO-B1.0 catalogue is:USNO-B1.0 0308-0442031 (J2000) 13 54 45.374 -59 09 03.52 mag. B2=15.52 R2 =15.12Our confirmation image (click on it for a bigger version):Below an animation showing a comparison between our confirmation image and the archive POSS2/UKSTU plate (R Filter - 1999).
