JUPITER SKETCH 4.16.04

Hi Richard,

Really good seeing conditions as the evening, April 16.2004, progressed.

Of note was the very marbled appearance of the NEB.

Festoons were well defined with the one just preceding the CM being dark.

The sloping dark rift in the SEB also well define. Just south of the rift SEB appeared somewhat brightened.

The southern NPR had a large brightening in the following half that was quite a bit wider than the NNTez is usually. Its somewhat overemphasized in my sketch so you can see it better.

The STB sloped southward on the following side. The northern edge of the SPR was much darker than usual.

I think System 1 @ 43 and System 2 @ 298. That's a rough estimate.

Best, Sol Robbins

Great sketch Sol, I noticed a bay in the N.E.B. just after the large festoon near the C.M. in your sketch but it may have been a contrast feature,the blue festoons really look dark with a #21orange filter,have you tried to use one on Jupiter?Again great sketch you really set the standard on Jupiter,both you and Carlos

Sol,

An excellent observation of Jupiter. The NEB has a marbled appearance at this time, as you point out, including bright rifts and dark condensations. The SEB and STB are also interesting. I too have noted bright regions within the NPR in the past. I look forward to your future observations.

Carlos
