Possible new nova in Centaurus. Discovered by John Seach, Chatsworth Island, NSW Australia. Instrument DSLR with 50 mm f/1.0 lens. Visible on 6 images, limiting magnitude 11. Nothing visible on image taken with same instrument on November 26.69 UT 2013 limiting magnitude 11. Nothing visible on variable star index, DSS2-red, or minor planet checker.

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 this 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 =15.12.
