I think actually the object is egressing from Earth's shadow at every pass, which makes sense given the northern hemisphere's summer shadow geometry. This happens at "max altitude" because it isn't visible until that point. Correct me if I missed something, Chris.

That just can't be, can it? What gives Chris?
