We discuss new intermediate-band photometric and spectroscopic observations of the totally eclipsing binary system S Cancri, and new photometric solutions using the 1992 version of the Wilson-Devinney code, updated with modern stellar atmospheres subroutines. We demonstrate that this aged Algol is probably now a detached system, helping to explain its relative inactivity. The effect of a thin extended atmosphere around the cool star is evident in ultraviolet solutions. We also present spectroscopic evidence of this extended atmosphere. A lack of photometric complications at longer wavelengths make S Cnc a prime candidate for a more precise determination of its fundamental stellar properties.
