Jupiter Sketch - 04/14/04

This is my first time sketching Jupiter, so please excuse the poor rendition. I normally image with CCD, but I wasn't able to setup that equipment tonight, and the seeing was so exceptional that I decided to try my hand at sketching.

Seeing held consistently at around 8, and often "popped in" to 9 or 10.

The most interesting area was along the NEZ, where I observed a very large whitish oval, similar in size and shape to the GRS. Preceding this on the S edge of the NEB was a very dark and large region which bulged S into the NEZ. The S edge of the NEB preceding this also had a "wavy" appearance, with two more areas of "bulge" into the NEZ.

I also observed two main festoons that appeared to be branching through the NEZ. Numerous other fainter festoons were visible, and had an almost "spiderweb" look to them throughout the EZ.

The rest of the major details I tried to capture in my sketch. Observations were made using an 8" f/5 newtonian @250X and 500X. No filters were used.

Comments/critiques appreciated!

Thanks,

-Jake
