- Note the new dusky oval within the southern
region of the STrZ just e. of the CM and seemingly associated with the south
edge of the SEBs. Also, note the clearly delineated development of the large
bright diagonal RIFT in the NEB.
The oval BA is clearly on the pr. side of the
longitudinal center of the GRS at this time. Note the continued development
both in intensity and eastward elongation of the dark streak pr. the GRS within
the mid latitudes of the STrZ. Oval BA is beginning to appear quite dusky and
losing it brilliance attained only days earlier and the perimeter
"border" has now reverted to an amophous brownish spreading of clouds
rather than a distinct peripheral outline.
"jupiter0224B" -
http://www.arksky.org/asoimg/jupiter0224b.jpg
Seeing very poor.
GRS measured at center = 76.4 (II) / 166.8 (III).
Note the intensity of the area immediately pr. oval BA. BA is now
clearly east of the longitudinal center of the GRS by a bit. Growing dark intensity fol. GRS and BA intersection area, and much
disjointed current evident in this area. Notice the tremendous development and
intensity of the great NEB RIFT near the CM in this shot.

One image from tonight's effort due to
increasing clouds and very poor seeing conditions. Interesting development
since last night (Feb. 24, however).

Hello Geoff and all -
You are correct
that the very dark spot IS Europa's shadow (that WOULD be an interesting feature
if it were a new dark oval!!)...
I was referring to the very small dark spot
near a white oval area immediately following the GRS, much smaller and less
intense that Europa's shadow!
Thanks - and I am glad you mention this so
that I can clarify if it was confusing.
As astute an observer as you are, if it confused you then certainly it
did everyone!
Look for that little spot very close and to
the right of the GRS in the image "jupiter0225a".
Thanks!

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.

Note the dark
streak in SSTB, immediately following the disturbed area behind oval BA; this
appears to "merge" within the active area fol. BA.

Seeing Good -
compare this CCD black and white image with that of "jupiter0227c"
taken only minutes before. The results of the convergence of the GRS and oval
BA is quite clear in this high contrast view.

Seeing very poor with intermittent clouds.
Note the dark small spot due south (above
in image) the GRS....this,
according to the ASO records, is not a satellite shadow so likely is a
transient and new dark spot within the STZ.
Note the increasing intensity of activity surrounding the GRS and BA.

Seeing fair to good. Note the intensely
bright NEB oval WS-4 just east (left)of CM, followed by barge B-1 which
appears to now be intersecting the fol. edge of WS-4. Note also the very fine activity that appears to be beginning
near the CM and following within the STrZ, this perhaps related to the
associated activity that has developed in that current during recent
weeks. Also, intensification of the NTB
begins very near this CM.

Seeing good; note the very active regions
surrounding the GRS and the intense darkening of the southern 1/2 of the GRS.
Oval BA now very dusky and appears to have a faint line of delineation N-S
across its mid-point.
Considerable darkening between STB current
and southern edge of GRS.

We have been totally socked in for 10 days
with heavy rain and lingering fogs.
Clearing last night but seeing was impossible to even focus to image.
Worst possible seeing conditions tonight as
well. Image obtained only to monitor converging white spots in SSTC (top, above GRS). The two SSTC converging spots can
be seen nearly on the CM (appears
a bit to the pr. side of CM, about 79 deg. System II).
Shadow is that of IO.
