The galactic foreground reddening in the direction of the nearby triangulum galaxy M33
Observations of 314 stars with the uvby-beta photometric system are usedto establish the reddening in the direction of the nearby Triangulumgalaxy M33. Color excesses are obtained for 151 A and F type stars in a1 deg 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 sixsuspected variable stars, as well as ten observations of V Triangulum, aBeta Lyrae eclipsing variable.
