We performed some follow-up of this object remotely through the 2.0-m f/10.0 Ritchey-Chretien + CCD of "Faulkes Telescope South" (MPC Code - E10). On our images taken on September 07.50, 2011 we can confirm the presence of an optical counterpart with filtered R-Bessel CCD magnitude 9.1 (USNO-B1.0 Catalogue reference stars) at coordinates: R.A. = 16 36 44.29, Decl.= -41 32 37.7 (equinox 2000.0; USNO-B1.0 catalogue reference stars). According to VIZIER there is a 15.08 R1 magnitude star at 0.060 arcseconds from the transient position (USNO-B1.0 0484-0459316).

I confirmed this possible nova using 31.7cm Ritchey-Chretien telescope(fl=1910mm)+SBIG ST-10 camera at Officer, Australia(Global-rent-a-scope). Photometric results are 11.88B, 10.73V, 9.75Rc and 8.77Ic on 7.5256-7.5288 Sep. 2011 UT. Position end figures are 44.28 and 37.58.

We performed low-resolution optical spectroscopic observations (R about 580) of PNV J16364440-4132340 on 2011 Sep. 7.42 using Araki telescope at Koyama Astronomical Observatory. The spectrum exhibits broad Balmer emissions and Fe II multiplet emissions on a highly reddened continuum light. The H-alpha emission line shows an asymmetric profiles with the FWZI about 6000 km/s. Other significant features are invisible in our spectrum. These results suggests that the object is an Fe II-type classical nova highly reddened by interstellar medium.
