[AZ-Observing] Jupiter Impact Mark

Sleep deprivation and cloud cover prevented me from attempting to  
observe this spot on the morning of July 20th. But tonight I was able  
to spend time with Jupiter in hopes of seeing the feature as it  
transited about 12:40 AM (July 21). As my 8 inch Dob cooled down, I  
worked on adjusting my eyes to details in the cloud belts. By 12:10  
AM, the seeing was improving, and Jupiter had rotated enough to make  
it clear that I was detecting a soft, dark spot near the southern  
pole. At 240X, I did not detect any structure in the feature, and it  
simply appeared as a soft, round spot, perhaps half the width of the  
south equatorial belt.

Over the next 45 minutes, I sketched its position, and all the other  
features I could detect. At times I've wished that I had taken up  
observing sooner so that I could have seen Shoemaker-Levy 9 pepper  
Jupiter with my own eyes. And what do you know, 15 years later, it's  
been hit again.

The sketch and full report can be found here:

I'm looking forward to what others end up observing, photographing  
and sketching!
