Seeing good and steady with high wind (temp. is 19dF) - Note the fine and
deep rift just east (right) of the CM in the NEB; also note the increasingly
dark/dusky oval at the south edge of the SEBs and into the STrZ just west of
the CM - the streak (SEBss?) pr. the GRS (far right) is growing in longitudinal
expanse to the east and also in intensity. SEBs is extremely
dark and thick immediately pr. the GRS.
Seeing good and steady with high wind (temp. is 20F) Oval BA has grown
SE to NW orientation and is very much "bean-shaped" at this time; note
darkening of its border on the pr (east) side. NOTE: some activity now
associated from BA on the SSE perimeter of GRS! (dark marking on GRS
perimeter). The dark barge associated with the conspicuous NEB rift is
growing in intensity and the rift is becoming still more increasingly
divided and distinctly wide.
Seeing is excellent. Note the dark marking within the center of the
the wonderful activity that has surfaced fol. oval BA....nice current
structure on both pr. and fol. ends of the GRS. The NEB rift is shown
clearly and appears to be establishing an even great separation than
in previous days.
A pretty nice view of "the other side" away from all the
convergences and interactions! A portrait of barge B-4....
Seeing good. Nice activity seen in NEZ....barge B-4 just east of CM
Note the dark streak in SSTB, immediately following the disturbed area
behind oval BA; this appears to "merge" within the active area fol.
Seeing Good - compare this CCD black and white image with that of
"jupiter0227c" taken only minutes before. The results of the
the GRS and oval BA is quite clear in this high contrast view.

Here are my latest images, and I'm currently processing the other Feb data.
The SEdisturbance is seen in the Feb26 images, perhaps now less conspicuous
on the CH4 band. The methane dark STB segments continue to be present, and
the NNTB oval is still methane bright.
The feb 27 images show the GRS, BA and SSTC Wos, NEB with B4 and the
extensive rift system (a mid-NEB barge / white spot is seen). The GRS and
BA in methane-band continue to present the morphology described in earlier
messages. A few CH4-bright clouds are seen in SEB following the GRS.
In clear and RGB images, a smal dark spot is seen immediately N of the GRS.
It is always impressive to see that even large /dark barges like B4 are
virtually invisible in IR.
