Man, this looks an awful lot like a dust devil in the distance. What do you think?

Heh, I was just starting a new topic for this one, but ya'll beat me to it.


A navcam from Spirit's Sol 421 shows a bright, conical feature rising from the plains west of the Columbia Hills. It appears to be in the same position from both L and R eyes. There is a bright strip on the ground extending north from its current position.
Here is a 2 frame animation comparing brightness enhanced left navcam images sol 421 to 420:

Since it was afternoon, the sun is to the west, so this may be a camera effect from looking in the direction of the sun although it would have to be a very strangely shaped one to account for these features.

In the anaglyph of the first one you can see it's out in the middle of the plain; if it's a camera trick it's a heck of a good one!

There have been some interesting shots of the sky recently that suggested to me at least that a lot of dust is getting kicked up. And of course we had our incident with the forward hazcams...

Edit: Sunspot beat me to it. smile.gif

What we need is one to come OVER HERE.....HELLOOO....YES YOU....GOT SOME NICE DIRTY SOLAR ARRAYS FOR YOU smile.gif

Likes buses - you wait 14 months then 2 come along at once - is it likely to be the same one photographed twice that far apart in only 80-something seconds? Theres a couple of km between the two locations, and MOC has often captured two or more devils in one image from orbit.

You're joking.

Actually - looking at the 'darkness' of the cells on those navcam images, I dont think you are!

wooOOoooowoooOOoooowaooowooo AT THE CAR WASH......

I've just wrapped up the biggest chunk of a huge animation project at work which I've had to do on my own that's involved a LOT of late nights and the client loves it - then Spirit spots a Dust Devil. Then another one. THE gets a doubling in power budget

Today = good day.
