Mutual Events of Galilean Satellites - bigmasterdrago - 2026-06-08

I've not yet found a method to predict these in the Event Finder. Years ago I used Occcult for this but no longer. Any help would be appreciated.

Thanks,
Kenneth Drake

Hi BMD,

I don't think that SkyTools 4 supports events between the Galilean satellites. It only supports transits, shadow transits, eclipses and occultations between a satellite and Jupiter itself. I checked SkyTools 3 and it works the same way. Since I no longer have SkyTools 2 installed on the computer, I can't try that one.

Perhaps the Skyhound can provide more information.

Yes, there are no mutual events, but that's something I should definitely implement at some point (puts it on the list).

Predictions of mutual events would be very interesting. Does anyone else do that?

FYI the "transit" in "shadow transit" is misspelled missing the "r" in the "Event Finder" dialog. The screen shot of the dialog in the Help also has the same misspelling. Something for a future update  Big Grin. It was like that in SkyTools 3 too, so not a big deal.
