The "transitions" do indeed take a finite time – a couple of minutes. I recently took some images of a double re-emergence of Io and Europa and they both gradually brightened before becoming full visible. A good illustration of how big the Galileans are.Nice to see you have a 9yr-old interested in these things!Best regards, Steve
