We report the discovery of two apparent novae in M31 on a co-added 900-s R-band CCD frame taken on Jun. 27.999 UT with the 0.65-m telescope at Ondrejov.

Designations, positions, offsets from the center of M31, and discovery magnitudes of the new objects are summarized in the following table:

 
 
  TOCP designation    CBAT designation  R.A. (J2000)  Dec. (J2000)  Offset R.A.  Offset Dec.  R-band mag 
 
PNV J00424097+4116171  M31N 2013-06a?   00 42 40.97   +41 16 17.1     37.8" W       8.6" N   17.0 +/- 0.15 
PNV J00422866+4114126  M31N 2013-06b?   00 42 28.66   +41 14 12.6    176.6" W     115.9" S   18.3 +/- 0.15 

The following additional R-band magnitudes were obtained using the 0.65-m telescope at Ondrejov for the PNV J00424097+4116171: Jun. 23.012 UT, [19.1; 27.980, 17.1 ± 0.15, and for the PNV J00422866+4114126: Jun. 23.012, [20.3; 27.989, 18.3 ± 0.15.
