Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan report the discovery of a possible nova (mag.= 17.1) in M31 on nine 60-s unfiltered CCD frames taken around 2016 Nov. 04.44058 UT,( limiting magnitude = 19.5 ) using a 0.50-m f/6.8 reflector (+FLI 1001E camera). as follows We report that this star locates 28" west and 145" south from the center of galaxy. Nothing is visible at this location on our past frames taken on 2016 Nov. 02.473 UT ( limiting magnitude = 19.2 ) and Nov. 03.453 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 41s80, 42"3, distance 1".0, magnitudes V=22.3, B=23.9, R=21.0,

Sara A Lopez, WeiKang Zheng and Alexei V. Filippenko (UC Berkeley) report the independent LOSS discovery of PNV J00424181+4113433 (=kait-16bq) on an unfiltered KAIT images taken at Nov. 05.258 UT with clear band mag (close to R) of 16.2.
