Contrary to what was formerly believed, VV Scl is not an eclipsing star but an Alpha CVn type variable with period P = 5.0976 +/- 0.0001 d. The range of the luminosity variation is remarkably large for an Ap star, especially in B of Johnson's system, and in b and mostly in v of Stromgren's one. A secondary minimum appears near the maximum in B, b, an v. The main minima are in phase in all colors.
