For telemetry purposes it would make an interesting point to watch live
telemetry as the satellite passes from light to dark, or vice versa, and
notice the change of the charge current and voltage and temps of the solar
It would also be used for trying to visually see the object. Especially
helpful when the observer is in darkness but the satellite is illuminated.
Just last week I saw the ISS pass over while it was fairly dark, not
complete, yet plenty of sunlight at 200 or so miles above earth.
