Jupiter, August 1

[bird (Anthony Wesley)]

The seeing here was very poor last night, but at least the skies were
clear for a change...

This image shows how the black impact mark on Jupiter is evolving - the
main body of the dark cloud is moving westward (to the right as we see
it here), although it appears that a small stream of dark material is
also being pulled down and in the opposite direction - perhaps around a
cyclone or some other localised weather feature?

Io is also visible along with its shadow.

hasnt that impact mark streched out!!! Well done Anthony

It's great to see the BSE evolve.
I am disapointed I have not seen it with my own eyes yet.

[RB (Andrew)]

Awesome stuff Anthony !
I agree, it's amazing how much it's stretched out.

Well done Anthony,

Two weeks on and still very distinct.

It is most interesting tracking the changing morphology of the impact region. The hook that is developing would seem to be affected by the shear from the winds at the intersection of the South Polar and Temperate Zones. This image depicts these two zones quite nicely.

ps the "hook" shape in the black streak appears to be material being recirculated around one of the orange polar spots. You can see that spot more clearly in this image:

which was taken in much better seeing.

cheers, Bird

Hi Anthony, while processing my data from this morning, July 4th, I have an image that supports your premise regarding the hook being influenced by the winds circulating around a polar spot.

The end of the hook has completely wrapped around a lighter spot.
Hope to be able to post images before tonights imaging session.

Cheers
Trevor

It's fantastic being kept up to date with the changes in the impact zone. Thanks Anthony for all the added info it's fascinating.

We will wait with interest to see your image Trevor
