8 Hour Jupiter Session...

[Paul G. Abel]

Greetings all!!

Attached are 5 disk drawings and a strip map I made on the night of 05-06 November 2012. After a month of almost continual cloud cover, the clouds parted and I was able to observe the planet from 2200UT- 0510UT. The main of rthing of interest was an enormous rift which was present in the NEB. The rift was rather obvious, and by making transit timings, I estimated it to be some 35 degrees long. It was hard to say if the rift was one long rift or a series of smaller ones whose boundaries were beyond the resolution of the telescope.

By 0407UT, oval BA and the GRS were on show. It seemed to me that BA had more colour than the GRS and was darker and more prominant.

Best wishes,

Nice set of drawings Paul.

Lovely drawings Paul. I have definite hints of a rift in the NEB from my images on the same night. Possibly two parallel rifts, in fact, at a slight angle to the equator.

Paul,

Those are very good drawings. i admire your artistry and dedication. I struggle to draw a straight line with a ruler - never mind sketching the universe!

lovely drawings indeed well done

[LukeSkywatcher]

Those are some impressive sketches. I'd need a ruler to keep my ruler straight to draw a straight line.

really superb effort and as usual a very high standard of drawing. fabulous.

They are amazing images, and such dedication to have an 8 hour session!

One question, what does 'Oval BA' and 'NEB' stand for? Im sure i probably know, but just cant get the abbreviations!

[JamesF]

"Oval BA" is the smaller spot near the Great Red Spot (GRS).

"NEB" is Northern Equatorial Band.

There are some nice images and information about Oval BA here, actually:
