Could that be explained by both Earth's rotation and the polar temperature?

Lutetia flyby navigation to start end of May http://sci.esa.int/science-e/www/object/in...fobjectid=47040
Note also that Rosetta's instruments have been used to collect a lightcurve of Vesta recently

Incidentally, is there a particular method for pronouncing Lutetia? Is it phonetic or what? It's bothered me for a while and I'd like to clear it up before Rosetta gets any closer. wink.gif

I've been going with LOOT-eh-shee-ah. Not sure if it is right, though.

I think Paolo's version is closer, but I've also heard it said as loo-TET'-see-ah

If Occam had heard my theory, things would be very different now.

I'd have thought "Loo-TAY-shee-ah" myself...

Well, since it is the Latin name for Paris, I would defer to our French members.

Okay, I'll play: "Loo-TEE-sha". smile.gif

The Wikipedia article says it's /ljuːˈtiːʃiə/ (lew-TEE-shee-uh) but also says it's possible to pronounce it as Latin (Lutētia), that is, loo-TAY-tee-ah.

There are two very interesting papers on adaptive optics observations of Lutetia on arXiv today:
Physical properties of ESA/NASA Rosetta target asteroid (21) Lutetia: Shape and flyby geometry
The triaxial ellipsoid dimensions, rotational pole, and bulk density of ESA/NASA Rosetta target asteroid (21) Lutetia
turns out Lutetia spins on its side like Uranus, and one entire hemisphere will not be illuminated when Rosetta swings by. As for the shape,

QUOTE
asteroid (21) Lutetia is well described by a wedge of Camembert cheese (justifying the Parisian name of Lutetia)

Rosetta has started imaging Lutetia. Not much to see yet. The images are used for navigation purposes.

Can't see the moons or rings or volcanoes yet . . . .


Reassuring the craft is on target and the trajectory tweaks are being computed. Getting pretty excited to see this rock up close.
