Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan report a discovery of possible nova (mag.= 8.8) in Sct on two 40-s unfiltered CCD frames taken around 2017 Jul. 26.51346 UT ( limiting magnitude=13.3 ), using a 120-mm f/4 camera lens (+FLI 09000 camera). We have confirmed immediately the appearance of our discovery this PN on five 20-s unfiltered CCD frames taken around 2017 Jul 26.5344 UT ( limiting magnitude=17.1 ), using a 0.50-m f/6.8 reflector (+FLI 1001E camera). (lens magnitude of referred catalogue Hipparcos, others reference catalogue GSC-ACT) Nothing is visible at this location on one past survey frames taken on 2017 Jul 16.533 UT(limiting mag.= 13.9) nor on DSS, USNO-B1.0, We have checked in Minor Planets. nearest star in USNO B1.0 has position end figures 45s86, 52"4, distance 3"5, magnitudes B2=18.42 R2=18.36

TCP J18314588-1418559 (see Itagaki-san's brief comment above) and PNV J18314593-1418557 are both identical with ASASSN-17hx, a spectroscopically confirmed Galactic nova (cf. ATel #10527) that was already discovered on 2017 June 19.41 UT "during the ongoing All Sky Automated Survey for SuperNovae" (cf. ATels #10523 and #10524, 2017 June 23): http://www.astronomerstelegram.org/?read=10524 --- Patrick Schmeer (Saarbr├╝cken-Bischmisheim, Germany)
