We report the independent discovery of a probable nova in M81 (first reported by M. Henze et al. in ATel #9175) on a co-added 3960-s unfiltered CCD frame taken on 2016 Jun. 20.880 UT with the 0.65-m telescope at Ondrejov.
The new object designated PNV J09545398+6902340 is located at R.A. = 9h54m53s.98, Decl. = +69o02'34".0 (equinox 2000.0), which is 210.2" west and 81.1" south 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):
2016 Jun. 9.928 UT, [21.3; 20.880, 19.6 ± 0.2.
We thank J. Vrastil for getting M81 images on Jun. 9.928 UT.
