Light curve of the week: tidally distorted EB

This week we have an EB where the two stars get so close to one another that their gravitational pull distorts their shapes, changing it from a sphere to a rugby-ball type shape. The increase in surface area from this results in an increase in observed flux after the primary eclipse. If you look carefully you can also see a small secondary eclipse!
