Here are two images of Jupiter from this morning, one RGB and one CH4. The transparency was ok, only small amounts of cloud, but the seeing was not so good.
The images show the GRS setting to lower right, and the orange ring of Oval BA is quite visible near the centre of the image, it is also bright in the methane band. The other methane-bright feature in the northern hemisphere is the NNTZ-LRS, showing up faintly orange also in the colour image.
The SEB continues as before, with a thin green band at the boundary with the equatorial zone, corresponding to a change in altitude as shown in the methane image. Interestingly the GRS is also at a boundary in altitude change, although that is not visible at all in the colour image.
cheers, Bird
