Very turbulent seeing, but eeked out a couple of shots early.  NOTE:  the
very dark gray streak noted on 02-12-02 is seen clearly in the color image
just east of the CM; note the intensity of the related festoon best seen in
the B & W CCD image.  Very nice collection of ovals just SW of GRS.  Note
the "pea-shaped" characteristic of oval BA, now very nearly central to the
GRS, and its continuing increased size.

Hello all,

Here are my latest jupiter images (Feb 13).

The IR and CH4 images of BA appear to continue to present the appearance
already described. BA continues to be smaller in methane and both GRS and
BA are well separated and apparently undistorted.

There is extensive rift activity in NEB. I call your attention to the IR
bright (although small) rift present at about L1 205. It is associated with
a methane-bright cloud.

Large festoons, very dark in IR are seen.

The S Tr band oval continues to be methane bright.

I would also like to mention the the region immediately "f" the WOS-BA is
now partially occupied by lighter clouds, a fact that mey difficult the
visualization of the small oval that follows BA.

Good observations

Antonio
