Scientific paper

The interstellar reddening law is derived for 15 heavily reddened stars in the area which includes the North America and Pelican Nebulae and the dark cloud between them. The method is based on photometry of these stars in the Vilnius seven-color system and on their MK spectral types. The mean law in this area is very similar to the law for a much wider area in Cygnus derived earlier by other authors. It differs from the normal law by exhibiting somewhat stronger extinction in the violet and the near ultraviolet spectral region, i.e., it shows a smaller `knee' in the blue part of the spectrum.
