The shadows of the Galilean satellites #1 Io and #2 Europa will be simultaneously transiting Jupiter on Sunday 2019 OCT 13. Io itself will also be transiting. This will be an evening event for the eastern half of North America and afternoon out west.

Photos and descriptions of the transits would be welcome additions to this thread.
