Odd Jupiter feature
      #5684270 - 02/16/13 09:19 PM Attachment (39 downloads)

I've seen this feature before, but it always stands out as quite spherical, different from the ovals you sometime see nearer the poles. Does anyone have a larger, clearer shot of this handy?

Thanks!

Is it one of the moons? Io transited tonight, the shadow was not on Jupiter until about 7:30ish EST.

Here are four sequential images. The sphere appears almost glowing, seems to have different texture/albedo from nearby clouds.

I checked Starry Night, estimating you are -6 hours for UT for somewhere in the western US. Io was in transit at about that time. Best I can do for you, not knowing your location and if the computer clock time is correct.

I don't think that is Io, the spot stays consistent with the clouds. Io move much too fast with respect to the disk. I think it is a disturbance within the clouds itself.

Thanks for checking. It seems to be at about the clouds' level, so not a moon...it just seems strange that it's so spherical and distinct and seems to keep its integrity. Certainly not Earth meteorology! I'm hoping some better imaging by a larger scope might show more.

The captures were taken between about 10 and 12 the evening of 2/15/2013, MST.

I've attached another image from 2/1/2013 that shows the same feature.

Here is a HST image that shows a similar feature.

Below is a link to some multimedia that seems to show similar features forming at about the same latitudes. It may be a transitional stage in cloud dynamics...still, rather strange.

Maybe these two show it as well?

This is part of the enjoyment of planetary imaging. You never know what you might find. Twenty years ago such a feature may have been unobserved. This is why it's so great that we amateurs have been able to forge a good relationship with professionals.

That looks like it, David.

Paul, you're exactly right. When I was a kid I wanted to be an astronaut, but here and now we're 'virtual' astronauts, thanks to great technology and great community. I feel like my pictures are postcards, snapshots from my 'travels'.
