Hi all, Here is a montage from images over Oct - Dec showing the fading of the North Temperate Belt f. the GRS. The faded area spans almost 180 degs, and also has faded quickly - having almost completely disappeared in only 3 weeks. Compared to the belts appearance back in October this certainly represents quite a major change in its appearance. It will be interesting to see if the rest of the belt fades away also.

Rogers" Subject: Re: fading of NTB Hi Damian, Thanks for pointing out the fading of the NTB. It's about time!-- these fadings normally occur every 10 years and the last one was from 1988 to 1990. (The NTB was also faint during the Voyager encounters 10 years earlier.) It's fascinating that, as Hans-Joerg shows with the JUPOS chart, the phenomenon is beginning with faint sectors moving with the rapid N. Temperate Current B. These could be delineated by rifts similar to those in the NEB?-we need to check the highest-resolution images. No such detail has previously been reported in fadings of this belt.
