No really good seeing this week but some interesting remarks.
(RGB,B)
(IR,violet,UV)
The GRS looks to have quite intensified in color during the summer (T. Akutsu already commented about this). The comparison in the first set shows it has passed from pale pink to orange. Intensification of its color is associated to the SEB fading so it could be again an argument for this (the spot is also maybe accelerating ?)
Finally,the NEB expansion spots are amazingly dark,especially in violet/UV ! I have tried to see such spots during the preceding expansion events on 2004 (found) 2000 and 1996 (not sure) but they've never been that numerous and that conspicuous.
