The main thing that struck me while watching Callistro reappear was just how long it took to recover full brightness. Compared to Europa & Io, it seemed to take ages. ( I will try timing it next time).


Thinking about it, Callistro is a larger Moon, and being further out, it moves more slowly out of Jupiter's shadow than the inner Moons. (As per Kepler's Laws of Motion).
