Mutual Events - Jupiter's 4 Galilean Satellites

[CentaurZ]

During periods of about six months separated by about six years, mutual events occur involving the Galilean satellites occulting and transiting each other, with similar effects from their shadows. The next such period will commence on 2021 JAN 03 and end on 2021 JUN 26. 

Photos and descriptions of these events would be welcome additions to this thread. The timing predictions posted below should not vary by much more than one second among locations.

Today Jupiter's axial tilt relative to Earth is 0˚, placing its four Galilean satellite planes in the sweet spot for mutual occulting and transiting events.
