I detected PNV in M31 on my patrol CCD images taken with 0.43-m f/6.8 astrograph + FLI-PL6303E CCD camera + f/4.5 focal reducer (T21, iTelescope.NET, Mayhill, USA) There are no star in my images taken on Jan 3.0925 (limiting magnitude were around 19R). I checked stacked M31 images taken with same instruments before. As location of PNV is closed to nucleus of M31, I could not find any other good reference images, such as DSS. My confirmation images taken with 0.50-m f/6.8 astrograph + FLI ProLine PL11002M + f/4.5 focal reducer, Luminance filter is available at http://meineko.sakura.ne.jp/ccd/M31-130105-L.jpg Seiichiro Kiyota(Tsukuba, Japan).

Mag.= 16.7 observed by T. Noguchi, Chiba-ken, Japan, Position end figures 44s.18, 52".0 using 0.23-m f/6.3 Schmidt Cassegrain + unfiltered CCD. The limiting mag.= 18.0. See an image http://park8.wakwak.com/~ngc/images/PNVinM31_20130105.jpg

Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan observe of a possible nova .(mag.= 16.0) in M31 on four 40-s unfiltered CCD frames taken around 2013 Jan. 05.4865UT, (limiting magnitude = 19.5) using a Meade 200R 0.40-m f/9.8 reflector (+SBIG STL1001E camera). But prediscovery on 2013 Jan. 04.4617 UT mag=18.2 (limiting magnitude = 19.2). The nearest star in M31 catalogue (http://www.lowell.edu/users/massey/lgsurvey.html) has position end figures 44s29, 54."0, distance 2."2, magnitudes V=20.9, B=21.3, R=20.1

2013 01 06.1711

Mag.= 16.0, Position end figures 44s.11, 51".7 remotely using 0.25-m f/3.4 hyperbolic astrograph + unfiltered CCD (SBIG ST-10XME) at RAS observatory near Mayhill, NM, U.S.A. (H06). The limiting mag.= 18.0. http://space.geocities.jp/yusastar77/supernova/PNinM31_130106.htm
