Independently discovered by K. Hornoch, P. Kusnirak, and J. Vrastil, Astronomical Institute, Ondrejov, at R-band mag 19.0 +/- 0.15 on co-added 1080-s R-band CCD frame taken with the 0.65-m telescope at Ondrejov. The position of the nova candidate is R.A. = 0h42m57s.11, Decl. = +41o17'10".8 (equinox 2000.0), which is 144.1" east and 62.3" north of the center of M31.
