Polar caps: Both caps look bright, the south cap is
brighter and the north cap more extended than the south
cap.
SSTB: Some Ovals look bright but images are of
low resolution to recognize them all. Dark matter P-F of
them.
STB: Oval BA is very bright. The little
pink-pale spot at about CM225° creates a methane-dark S
feature.
The large feature passing GRS meridian is
methane-dark too.
STr.Z: Looks brighter in P. side of
GRS than F.
SEB: It has same difference in brightness
as the visual spectrum. A methane-bright plume is visible on the
rifted region F of the GRS. Bright
region around 75deg
(CM2)
on SEBn as a result of SED.
EZ: Very active zone. At
about 60-75° (CM.2) on the P side of SED there is a dark
projection. EB is sectored and dark from about 150°-350°
(CM2).
EZn-NEBs: A very active area with 6-7 dark
projections (dark-blue in RGB) associated with bright areas on
the F side. There is a very bright plume
at around 135°.The
NEBs edge is largely covered with methane-bright haze, so the
NEBs dark projections appear to be separate from the
methane-dark NEB.
NEB: Brown barges are
methane-dark. NEBn is bright and WS/A-B and WS/Z are very
bright.
NTrZ: Is constantly bright in all length.
NTB:
The NTBs edge is also methane-bright but the rest is dark.
NNTB:
Some light dark sectors are present.
NNTZ: LRS-1 is
very bright but there are some more bright spots. LRS-2 at
around 355° is associated with a bright area.
