satellite trail as it spins it must reflect more light and thus seem brighter. it is also a refraction in the lens of the camera

Sometimes satellites are rotating or tumbling and change their reflectiveness in the middle of an orbit, but this is a pretty steep change!

Looking at SkyServer shows this is actually a different kind of artifact, probably a tracking problem.
