Scientific paper

Observations of 314 stars with the uvbyß photometric system are used to establish the reddening in the direction of the nearby Triangulum galaxy M33. Color excesses are obtained for 151 A and F type stars in a 1° radius centered around the galaxy. A color excess of E(b-y) = 0.057 mag (E(B-V) = 0.077 mag) is obtained for a distance modulus m-M = 10. A secondary result of this investigation is the discovery of six suspected variable stars, as well as ten observations of V Triangulum, a β Lyrae eclipsing variable.
