We report the discovery of an apparent nova in M81 on a co-added 2970-s unfiltered CCD frame taken on 2016 Jan. 30.200 UT with the 0.65-m telescope at Ondrejov.

The new object designated PNV J09551797+6904390 is located at R.A. = 9h55m17s.97, Decl. = +69o04'39".0 (equinox 2000.0), which is 81.5" west and 43.9" north of the center of M81 (see link to discovery image below).

The following unfiltered magnitudes were obtained using the 0.65-m telescope at Ondrejov (R-band magnitudes used from comparison stars):

2015 Dec. 30.889 UT, [21.6; 2016 Jan. 30.200, 19.7 ± 0.2.

We thank J. Vrastil for getting M81 images on Dec. 30.889 UT.
