2021 August 21: Triple Transit and Mutual Events

Note: Click on the image for more images (if that makes sense).

Personal note: In the 70's, I loved watching transits of the Jovian moons' shadows, and transits of the moons themselves on Jupiter's disk but for some reason I was never able to see a moon eclipse another, much less on Jupiter's disk, as seen from Earth. But I was able to see one moon occult another (no details retained :grin: ).
