Dear colleagues,
         I would like to inform you about independent discovery of apparent nova
in M31 galaxy:

Kamil Hornoch and Peter Kusnirak, Astronomical Institute, Ondrejov, report their
discovery of apparent nova in M31 on co-added 900-s R-band CCD frame taken
on May. 30.061 UT with the 0.65-m telescope at Ondrejov.
The new object is well visible on the co-added frame and faintly visible
on single images used for the co-added frame, but is not present on archive
images taken at Ondrejov.

Available R-band magnitudes, measured by Hornoch:
2011 May 10.075 UT, [19.2 (K. Hornoch, 0.65-m telescope at Ondrejov);
16.076, [19.1 (Hornoch); 30.061, 18.1 +/- 0.2 (Hornoch and P. Kusnirak,
0.65-m telescope at Ondrejov).

The new object designated PNV J00424359+4116378 is located at R.A. = 0h42m43s.59,
Decl. = +41o16'37".8 (equinox 2000.0), which is 8.3" west and 29.3" north
of the center of M31.

Best wishes,
