[Centaur]

I’ve determined that during the one o’clock hour CST in the morning of December 6, Jupiter’s Galilean satellite #4 Callisto will partially occult #2 Europa. This occultation will be particularly unusual in that it will last for nearly fifty minutes, since the two will have nearly the same apparent angular velocities relative to an earthbound observer. The partial occultation will begin at 01:00:42 CST and end at 01:50:17. At 01:27:46, about 3/8 of the diameter of Europa will be covered by Callisto. Similar mutual occultations/transits between Galilean satellites usually last only a very few minutes.

Thanks again for alerting us to this mutual Galilean Moon event, but it's cloudy now, and little chance of that changing. I'll be at work anyway, although with a clear sky, I could have taken my break to coincide with either first or last contacts.
