2010CBET.2516....1N

An apparent nova in the galaxy M31 has been discovered by several different observers. Koichi Nishiyama, Kurume, Japan; and Fujio Kabashima, Miyaki, Japan, report the discovery of a possible nova of mag 17.8 on ten 40-s unfiltered CCD frames (limiting magnitude 19.5) taken around Oct. 29.478 UT with 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 a Digitized Sky Survey image from 1986 Nov. 27 (limiting red mag 18.7). The nearest star in the Massey M31 catalogue (cf. website URL http://www.lowell.edu/users/massey/lgsurvey.html) has position end figures 37s.01, 30".8 (distance 1".4; magnitudes V = 22.6, B = 23.4, R = 22.5).
