I report the discovery of two probable novae in M81 on a co-added 3870-s unfiltered CCD frame taken on 2014 Jun. 6.922 UT with the 0.65-m telescope at Ondrejov.

Designations, positions, offsets from the center of M81, 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.  Unfilt. mag 
PNV J09560098+6903513  M81N 2014-06a?   09 56 00.98   +69 03 51.3    149.0" E      3.8" S    20.4 +/- 0.25 
PNV J09554050+6904048  M81N 2014-06b?   09 55 40.50   +69 04 04.8     39.3" E      9.7" N    20.1 +/- 0.25 

Both two objects are not visible on a co-added 1800-s unfiltered CCD frame taken on 2014 May 31.880 UT with the 0.65-m telescope at Ondrejov down to limiting unfiltered magnitude of 21.1 (R-band magnitudes used from comparison stars).
