PNV J09553757+6900146 transient in M81 was observed with the 2m RCC telescope of BNAO Rozhen, equipped with the FoReRo2 instrument starting on February 07.729 (middle 07.736) and 07.745 (middle 07.752) 2016 UT in R and V bands respectively under a clear sky conditions and 1.5 arcsec seeing.
There 300 seconds exposures were acquired in the V and R bands, along with short 1 second calibration exposures for a total of 900 seconds in each filter. We measured V = 21.6 +/- 0.5 and R = 20.6 +/- 0.2, using the standards of de Vaucouleurs et al. 1994, located in the M81 field.
This corresponds to a V-R colour, equal to 1.0 +/- 0.5. Taking into account the R band photometry, published in ATel #8632, the nova has passed its maximum light. Further observations are encouraged.
