The Season of Mutual Phenomena

#1

Post by Graeme1858 »


Whilst researching stuff for the Forum Portal Astro Events Calender, I was looking for Jovian shadow transits because there's a couple of doubles this month and I found this in Sky and Telescope:

"Every six years the orbital plane of the four Galilean moons is edge-on with the Sun and Earth, and we enter the season of mutual phenomena, when the moons occult and eclipse one another. The season began on January 3rd when Europa partially eclipsed Io and finishes up on November 16th with a Ganymede-Io occultation. Although Jupiter is still low at dawn it inches higher every morning and will soon be in good view."

Now there's a viewing challenge!
