Here are yesterday's images, which span the L1 longitudes of the SE disturbance (quite evidente in methane light and R and IR.
The methane bright redish NNTZ oval (also methane bright) is seen.
A bright (particularly with clear, G and B filters) NEBs cloud associated with a proeminent bluish festoon is also depicted, but it is less apparent in IR and not seen in methane.
There is a very slight decrease of EZ brightness in methane light associated with such prominent festoons.
As reported earlier, some STB segments are evidently dark in methane light.
They correspond to inconspicuous slightly redish segments in visible light (also slightly dark in IR). It appears that the nearby STZ displays two fuzzy greyish oval patterns that look darker than the adjacent white STB.
Callisto can be seen in transit in some of the images.
