Abstract (from CDS):

K. Hornoch, Lelekovice, Czech Republic, reports the discovery of two apparent novae in M31 by P. Kusnirak (first object), M. Wolf (second object), and himself (both objects) on CCD R-band images taken by them and L. Sarounova with the 0.65-m reflector at Ondrejov. The first new object is located at R.A. = 0h43m26s.84, Decl. = +41o16'40".8 (equinox 2000.0), which is 479" west and 32" north of the center of M31. R-band magnitudes for this object from Hornoch: Aug. 2.974 UT, [20.5; 3.960, 19.2:; 4.901, 18.8; 6.997, 17.8; 7.982, 17.3; 9.070, 17.8; 10.005, 18.3; 10.956, 17.7; 12.057, 18.3; 15.943, 17.6; 23.902, 17.5; 24.060, 17.6; 28.899, 18.1; 31.915, 18.6; Sept. 3.018, 18.6; 3.868, 18.7; 4.819, 19.0; 5.058, 18.9; 6.930, 19.0; 8.929, 18.3; 9.893, 18.3; on Aug. 24.063, V = 17.6. The second new object is located at R.A. = 0h42m40s.25, Decl. = +41o14'42".9, which is 46" west and 86" south of the center of M31; R-band magnitudes for this object from Hornoch: Aug. 24.060, [19.8; 28.899, [19.1; 31.915, 18.3; 31.938, 18.0; 31.952, 17.8; Sept. 3.018, 17.5; 3.868, 17.6; 4.841, 18.2; 5.862, 18.1; 6.930, 18.0; 8.953, 18.1; 9.893, 18.4. Filippenko et al. add that inspection of spectra, obtained at Lick (as described above) on Sept. 10, shows both objects to be novae with very strong H_alpha emission (FWHM about 2000 km/s); considerably weaker H_beta and Fe II may be visible, as well.
