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 Sep. 30.44605 UT ( limiting magnitude=13.4 ), 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 Sep 30.4621 UT ( limiting magnitude=16.9 ), 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 Jul 11.539 UT(limiting mag.= 13.5) and 12.571 UT (limiting mag.= 13.7) nor on DSS, USNO-B1.0, We have checked in Minor Planets. nearest star in USNO B1.0 has position end figures 12s929, 29"93, distance 6"6, magnitudes B2=17.62 R2=15.06

A low-dispersion spectrum of this possible nova was obtained by K. Ayani, Bisei Astronomical Observatory(BAO), Ibara-shi, Okayama, Japan, with the BAO 1-m telescope. The spectrum was that of a M-type star. It is not a nova.
