U Sco in the B band. U Sco has a prominent and deep eclipse. Outside of the eclipse, the light curve is flat (with no apparent secondary eclipse) with substantial flickering. The quiescent level appears to change from orbit-to-orbit from B = 18.8 to B = 18.0, even though the average is close to B = 18.5. This folded light curve is from my Cerro Tololo and Kitt Peak data from 1988 to 1998.
