Scientific paper

Individual UV extinction curves for nine stars located in the direction of h and Chi Persei in the distance range 0.6-4.4 kpc are presented. The observations were made with the International Ultraviolet Explorer (IUE) in the low dispersion mode with large aperture. The sample has been enlarged by the use of available UV and visible data for 32 reddened stars with distances r not less than 2 kpc located in the same direction. It is found that the mean interstellar extinction curve for the stars located in the Perseus arm shows significantly higher extinction shortward of 2000 A than the galactic mean.
