Jupiter

Here is a drawing I made of Jupiter. The sky's in Cheshire cleared shortly after 21:30bst, and by 22:30 there was know cloud. But it was very damp, and very clear. Transparency was excellent, 1 on my scale of 1 to 3. NGC884-869 were very clear with my unaided eye.

But with such good transparency the seeing for planets wasn't that hot. Ant III/IV so I was restricted to using low power x160 with my 250mm Newtonian.

Jupiter was showing his bland side tonight, however, there was still plenty to see. All the belt's and zones were clearly visible during moments of steady seeing. The North Equatorial belt is still very dark, and brown, whilst the SEB is still absent. There was a small white oval moving east-west in the NEB and I have seen this before.

I would like to know which oval this is?

Both polar regions were clearly visible; The NPR was considerably paler then the darker SPR. The GRS wasn't visible.

I used a sketch pad and the circle, is drawn using a coaster. Through I think, the circle is a little on the large side.
