Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan report a discovery of possible nova (mag.= 11.1) in Sco on two 40-s unfiltered CCD frames taken around 2013 June. 03.6146 UT ( limiting magnitude=13.5 ), using a 105-mm f/4 camera lens (+SBIG STL6303E camera). We have confirmed immediately the appearance of our discovery this PN on five 3-s unfiltered CCD frames taken around 2013 June 03.6728 UT ( limiting magnitude=17.4 ), using a Meade 200R 0.40-m f/9.8 reflector (+SBIG STL1001E camera). (lens magnitude of referred catalogue Hipparcos, others reference catalogue GSC-ACT) Nothing is visible at this location on two past survey frames taken on 2013 May 17.694 UT(limiting mag.= 13.4) and 30.647 UT (limiting mag.= 13.4) nor on 2MASS,USNO-B1.0, We have checked in Minor Planets. nearest star in USNO B1.0 has position end figures 59s515, 25"68, distance 4".2, magnitudes R2=18.18 I=17.4

Following the posting on the Central Bureau's Transient Object Confirmation Page about a possible Nova in Sco (TOCP Designation: PNV J17335943-3606216) we performed some follow-up of this object remotely through the 0.50-m f/6.8 astrograph + CCD + f/4.5 focal reducer of ITelescope network (MPC Code Q62 - Siding Spring, AU). On our images taken on June 03.7, 2013 we can confirm the presence of an optical counterpart with unfiltered CCD magnitude 11.5 at coordinates: R.A. = 17 33 59.44, Decl.= -36 06 20.7 (equinox 2000.0; UCAC-3 catalogue reference stars).

I confirmed this PNV at mg 11.9C on my survey images taken with 100mm F4 lens and unfiltered STL-6303E.Akira Takao in Kitakyushu-City,Japan.
