Koichi Nishiyama, Kurume, Japan; and Fujio Kabashima, Miyaki, Japan, report their independent discovery of M31N 2010-12c at mag 16.4 on six 40-s unfiltered CCD frames (limiting magnitude 19.2) taken around Dec. 16.526 UT using a Meade 200R 0.40-m f/9.8 reflector (+ SBIG STL1001E camera). The measure the variable's position to be R.A. = 0:42:56.65, Decl. = +41:17:21.5 (equinox 2000.0), which is 139" east and 73" north of the center of the galaxy M31. Nothing is visible at this position on their past frames taken on Dec. 11.446 (limiting magnitude 19.2) and 14.476 (limiting mag 19.0) or on the Digitized Sky Survey from 1986 Nov. 27 (limiting red mag 18.9) and 1993 Oct. 21 (limiting infrared mag 17.9). The note that the nearest star in the M31 catalogue (http://www.lowell.edu/users/massey/lgsurvey.html) is only 0".5 away (position end figures 56s.69, 21".8; magnitudes V = 21.7, B = 22.5, R = 21.0).
