This is my second posting on Alpo. Last time I photographed Jupiter was at the end of October and I notice that NEB has become significantly thiner.
Could this be an early indication that NEBs is about to disappear just like SEB did in 2010?
The moons are Ganymede and Europa to the left and Io to the right.

Please note the bright white spot in methan absorption band in the North polar area.
As some people asked me,I made a comparision between images done with WinJupos derotation function and the best of the
individual images used for this derotation,under each filter. The derotation images have been further processed
(by a simple gaussian mask) to improve details while not rising the noise more than for the individual images.

Oval BA and spot Z are well placed on the disk. Oval BA's perimeter is very faded making it quite difficult to see during capture.
