Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan report the discovery of a possible nova (mag.= 16.3) in M31 on eight 60-s unfiltered CCD frames taken around 2016 July 27.69825 UT, ( limiting magnitude = 19.3 ) using a 0.50-m f/6.8 reflector (+FLI 1001E camera). as follows We report that this star locates 222" east and 59" north from the center of galaxy. Nothing is visible at this location on our past frames taken on 2016 July 21.696 UT ( limiting magnitude = 19.1 ) and July 22.764UT(limiting magnitude =19.1). 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 04s05, 07"4, distance 0"8, magnitudes V=22.2, B=22.5, R=21.0, And very near Nova M31 2007-07a, 04s05 08"3 distans 0"7

E. Conseil confirms the presence of a new transient at the reported location using Slooh space robotic telescope T2 (17" Corrected Dall Kirkham + FLI PL 16803) at Mt Teide, Canary Islands. Mag CV = 17.5 (UCAC4 V for ref, limiting mag : 18.8) The object was not visible on 3 images taken on 2016-07-25.1056 with the same equipment (limiting magCV 19).

Sanyum Channa, WeiKang Zheng and Alexei V. Filippenko (UC Berkeley) report the independent LOSS discovery of PNV J00430400+4117079 (=kait-16aj) on an unfiltered KAIT images taken at July 27.479 UT with clear band mag (close to R) of 16.0. Nothing was visible at this location on our past image taken on July 26.474 UT (limiting magnitude = 18.5). A finding chart is posted at http://w.astro.berkeley.edu/~zwk/findingchart/KAIT-16aj.jpg
