 Because Amalthea is in synchronous rotation, Jupiter would not appear to move, and would not be visible from one side of Amalthea.The Sun would disappear behind Jupiter's bulk for an hour and a half each revolution, and Amalthea's short rotation period gives it just under six hours of daylight.Though Jupiter would appear 900 times brighter than the full moon, its light would be spread over an area some 8500 times greater and it would not look as bright per surface unit.
