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).
