Europa, Io and Jupiter (the big "Juju":-)
Hello, this evening at 07:40 PM UT, occured this: Europa occulted Io (I missed it unfortunately, because of damn clouds) just before crossing Jupiter:
Then later on (I saw it), Io crossed the disk, not without previously, letting its shadow on the planet. Europa's shadow was a lot harder to spot.
(Thanks to Starry Night; you can simulate it too if you have it)
