Abstract. We present a UBVR stellar photometry in the spiral galaxy NGC6946. The colour-magnitude (V,B-V) and colour-colour (U-B,B-V) diagrams were built. The internal and foreground reddening was determined. Using the method of the three brightest blue stars we estimated the distance to the galaxy, that appeared to be approximately 6 Mpc. These are preliminary results and they may a little change during the further work.
