 Cool eh?  I'm afraid my IcySats knowledge is terrible - and I just go from what the raw images website tells me..and it says Tethys....if anyone can fill me in on the 'other' one Hands up if you thought the darker moon was going to go infront of the brighter moon ! Doug |

So Tethys is the 'static' one which was targetted, and Dione moved past.
Just doing the Pandora + Ring movie that's on the raw's as well. GET OUT THE INTERNET CAFE PHIL, for the only day of the year, it's Sunny in the UK and you're WASTING it  Doug |

Wonderful animations Doug !!
And of course I thought Dione was in front of Tethys too  In the darkness of space, the mind assigns the larger to the closer

I too thought the lower moon (Dione?) would pass in front of the upper.. is it bigger? I suppose it is, a little.. but even if it were smaller I suspect I would have expected the lower moon to pass in front. The question is - why? I think it's because the lower moon is moving, whereas the upper appears to be stationary. Alternatively, it could be because the upper moon is higher. I'm sure neurologist types have studied this sort of thing exhaustively regardless, and uhh, yeah, cool animation.

I think it's because we're used to seeing eclipses and occultations, where the moving, closer object passes in front of the stationary, distant object.

What's up with that bobbing and weaving? I feel like I need some sea-sickness pills.

QUOTE (ilbasso @ Sep 13 2005, 06:13 PM) I think it's because we're used to seeing eclipses and occultations, where the moving, closer object passes in front of the stationary, distant object.  More likely because our visual system puts lower things closer, ie look at a landscape and everything "lower" in your minds' eye the brain interprets as "closer". -------------------- Space Enthusiast Richard Hendricks

Nope - it's just clear filtered stuff
I mean - you could fake some, but there's no colour to be had from the data. Doug |

That moon occulting Pandora could well be Janus rather than Hyperion -- I've already seen some views of Janus from a side that gave it that general shape.
