Jupiter sketch October 30 - 2012
      #5498883 - 11/01/12 03:23 AM Attachment (46 downloads)

hi all,

this night later I had a little better seeing.
I used a 200/1600mm Dobson from a good friend.
I saw different darkness inside the GRS !
The BA was not strong in contrast.
I measurded his position at II 170°.

30.10.2012, 22:50 UT, V 178x and 213x without filter

I 305° II 164°

I measured the GRS after sketching again by II 183° !

Bye Christian

Christian, "I saw different darkness inside the GRS !" Outstanding. Yea, I see the same thing, but not sure if it's GRS detail or a contrast effect caused by the brighter band across the GRS.

To me, the GRS has a two toned appearance at lower power. I did manage the entire oval form at 300x, but did not note any internal features at that magnification.

Nice observation, Christian. Bye.

hi Norme, hi Andre,

thanks a lot.

I saw for several years darker parts inside
the GRS so I think itīs yet real too.

Jef, You got the good weather from West in Belgium
mostly hours before it come to me .
Sharpen your pencil and take Your redlight and a paper .

Bye Christian

Cristian, outstanding detail renderings here. I very much enjoy the shading you've managed to see in the GRS. You make me wish I had better seeing conditions.

Christian,

Two fine observations. A very good luck at Oval BA and the super storm GRS. You saw a little of the turbulence following the GRS, too.

Your timing of the GRS at 183° matches the latest S&T info (184°).

Super storm Sandy has put a stop to astronomy here. We still have clouds and plenty of turbulence.
