[AZ-Observing] Re: Jupiter Impact Mark

Jupiter put on a great show tonight!

The impact feature is still hanging on and was readily visible  
through my 8 inch Dob at 120X and 240X. The best part was seeing it  
along with a beautiful shadow transit with Callisto hanging just  
outside Jupiter's following limb. It also provided a nice contrast  
for comparison of the two spots. Callisto's shadow was strikingly  
black, while the impact scar appeared more as a soft feature that  
seemed to take on the brownish color of the surrounding clouds. I  
spent more time getting a feel for the impact site itself, and did  
detect a horizontal elongation and slightly condensed appearance.

I had a couple moments of incredibly good seeing that showed up a  
lighter patch north of the impact scar and corresponded well to the  
position of a white spot in the area. I did not detect this as a hard  
oval, just as a subtle brightening in the area. Midway through my  
observation, high clouds moved in and foiled my attempts to finish up  
detail on the preceding edge before it rotated out of view, so the  
equatorial belts are a little plain in that part of the sketch. I  
finished the observation just as Callisto was dipping into Jupiter's  
profile. What a great view!
