Kamil Hornoch, Ondrejov Observatory, reports his discovery of another apparent nova in the galaxy M31 made on a co-added 1740-s R-band CCD frame taken with the 0.65-m telescope at Ondrejov on Mar. 17.765 UT; the new object is visible on single images used for the co-added image, but it is not present on numerous archival images taken at Lelekovice and Ondrejov back to 2002. The new object is also visible on a pre-discovery R-band CCD frame taken by Hornoch with the same instrumentation on Mar. 9.746. Designated M31N 2010-03b, the presumed nova is located at R.A. = 0:42:55.87, Decl. = +41:15:19.6 (equinox 2000.0), which is 130" east and 49" south of the center of M31. R-band magnitudes measured by Hornoch for M31N 2010-03b: 2010 Jan. 31.838, [21.1 (P. Kubanek, N. Morales, J. L. Ortiz, J. Gorosabel, and M. Jelinek, 1.23-m telescope at Calar Alto); Feb. 25.745, [20.0 (Hornoch, 0.65-m telescope at Ondrejov); Mar. 7.773, [19.7 (P. Kusnirak, 0.65-m telescope at Ondrejov); 9.746, 18.3 ± 0.3 (Hornoch); 17.765, 16.9 ± 0.1 (Hornoch); 18.763, 17.2 ± 0.1 (Hornoch, M. Wolf, and P. Zasche, 0.65-m telescope at Ondrejov).
