Abstract: Systematic properties of the transitions between high and low states in VY Scl-type CVs have been investigated as possible clues to the mechanism for the transitions. Much of the behavior is random, but a few trends emerge. There is a tendency for the transitions to become steeper during the fainter portion of the change from high to low as well as from low to high. We argue that this and related behaviors favor the idea of the low states being due to star spots on the secondary star, as they drift across the L1 point.
