Using the 50-cm La Silla ESO telescope, 2746 uvby measurements of the early-type double-lined eclipsing binary AL Scl have been obtained for the 1978-1981 period. An integration time between 10 and 20 sec per filter was necessary in the photometer to attain an accuracy of 0.2 percent. A mean error of better than about 0.05 mag was found for single measurements in all colors.
