Three independent discoveries of a nova in M31, here designated M31N 2010-10d, were reported, with details given below.

Koichi Nishiyama, Kurume, Japan; and Fujio Kabashima, Miyaki, Japan, report the discovery of a possible nova (mag 17.8) in M31 on ten 40-s unfiltered CCD frames (limiting magnitude 19.5) taken around Oct. 29.478 UT using a Meade 200R 0.40-m f/9.8 reflector (+ SBIG STL1001E camera). The new object is located at R.A. = 0:42:36.91, Decl. = +41:19:29.9 (equinox 2000.0), which is 84" west and 201" north of the center of the galaxy M31. Nothing is visible at this position on their past frames taken on Oct. 26.550 and 27.642 (limiting magnitude 19.3) or on the Digitized Sky Survey from 1986 Nov. 27 (limiting red mag 18.7). The nearest star in Massey's M31 catalogue (http://www.lowell.edu/users/massey/lgsurvey.html) is 1"-2" away (position end figures 37s.01, 30."8, magnitudes V = 22.6, B = 23.4, R = 22.5).
