Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan report the discovery of a possible nova (mag.= 17.2) in M31 on seven 60-s unfiltered CCD frames taken around 2016 Aug. 10.55410 UT, ( limiting magnitude = 19.2 ) using a 0.50-m f/6.8 reflector (+FLI 1001E camera). as follows We report that this star locates 536" west and 281" south from the center of galaxy. Nothing is visible at this location on our past frames taken on 2016 Aug. 08.615 UT ( limiting magnitude = 19.2 ) and Aug. 09.620 UT ( limiting magnitude = 19.2 ). We have checked in Minor Planets. Nothing is visible at the position of possible nova on the Digitized Sky Survey (POSS2/UKSTU) from 1986 Nov. 27 (limiting red mag 18.7) and 1993 Oct. 21 (limiting infrared mag 17.8). the nearest star in M31 catalogue (http://www.lowell.edu/users/massey/lgsurvey.html) has position end figures 56s86, 28"2, distance 0"8, magnitudes V=22.5, B=23.7, R=21.5,

Goni Halevi, WeiKang Zheng and Alexei V. Filippenko (UC Berkeley) report the independent LOSS discovery of PNV J00415682+4111276 (=kait-16av) on an unfiltered KAIT images taken at Aug. 11.411 UT with clear band mag (close to R) of 17.0. Nothing was visible at this location on our past image taken on Aug 08.389 UT (limiting magnitude = 19.2). A finding chart is posted at http://w.astro.berkeley.edu/~zwk/findingchart/KAIT-16av.jpg
