of the GRS.
To study the long-term changes of barge B-4, you can use the ASO
Image Archives Longitude Reference; merely go to:

and press "reset." Then type in a longitude CM2 range "From 130 To 170" and that will provide you with a chronological reference of all images of B-4 from January 26 into October of last year, centered on that feature.

Attached is a black and white STV-CCD image of Jupiter from

clearly make out two dusky ovals PRECEDING the GRS in the STrZ...the one
closest to the GRS pr. end is slightly offset to the south axially and smaller
than the more prominent one pr. it.

the second and third images ("b" and "c"), there is yet another
NEW very bright white spot that has emerged north (below in images) and very
close to the large oval BA.
Right now it appears that BA is attempting to traverse south of
the GRS...much of the early cloud interaction that I recorded during the past few
days has subsided, with what appears to be a clearly-defined border

Subject: More Aspects of BA and the GRS
I would like to refer you to three images obtained in the ASO Jupiter
Patrol last night (
http://www.arksky.org/asoimg/jupiter0127a_b.JPG
http://www.arksky.org/asoimg/jupiter0127c.jpg
1) note from images
"jupiter0127c" and "jupiter0127b" the distinct indication
of TWO "stacked" features with oval BA; you can see a clear
delineation and a faint border encompassing the perimeters of TWO ovals of
nearly equal color and intensity; these are oriented in a near north-south
orientation with their center longitudes nearly coincident.
Note that the more northerly of the two is a) smaller; b) has a
distinct red hue (see best in "jupiter0127b") and is offset slightly
WEST in relation to the larger feature, which is more coincident with the true
BA oval.
2) Note the COLOR of the GRS in
recent days....none of the ASO patrol images are processed with added color;
the GRS, particularly to the southern regions of it, has begun to demonstrate a
stronger hue of very subtle pink over previous weeks and appears to
"may" be intensifying within its southern 1/2.
3) Also note that there appear to be
several very vague brighter features actually preceding the GRS in the STrZ,
two that can be barely discerned immediately pr. the spot and several very
small ovals that appear "deflected" along the GRS southeastern
perimeter.
4) The very bright
http://www.arksky.org/asoimg/jupiter0127c.jpg
continues to show signs of rapid
subsidence in recent days; it once continued westward diagonally through the
NEB until a clear intersection with the incredibly prominent barge B-4, but now
remains only a short segment of its original self....
Although the oval BA is predicted to "make it out alive"
from its impending run-in with the GRS, I think that we should all still be very
attuned as often as possible for rapid developments in these areas.

I would appreciate it greatly if my correspondents here on the

Hello and thanks for your reply....
I DO HAVE A QUESTION, HOWEVER....I was noticing that your Jupiter
group has not been posting nor referring our images at all that we have been
sending for almost five months.
We have very prominently displayed the excellent links to their
site via our website, but all the contributions that we have sent your way
apparentlyare
not being used. Is there a reason for this and should we
cease sending the >images each night?
I was under the impression that the ASO Patrol Images were wanted
and welcomed, but to date none of our information has even been acknowledged by
your group!?
I would greatly appreciate an answer or perhaps just a note that
it is not necessary to send the daily Patrol images over. Thanks and thank you so much for
responding!

Hello. It sounds as if you have taken offense at my message of

whatever reasonwe have been sending information to some wrong locations from

I really did not see any reference whatsoever to your being
"slow" in my concern for attempting to determine if our information
was of any use to your organizations.....I had been told by the editor of Sky

Agustin -
Once again thank you for the excellent charting. This is a very valuable reference and one
that clearly demonstrates quickly "where we are headed" with the Red
Spot/BA interaction; from my observations AND you latter points on the chart
(#2), it appears that BA has already begun a slight acceleration relative to
the circulating current as well as to the GRS.
Referring to the ASO Sky Patrol images posted from last night
(Feb. 15 UT),
http://www.arksky.org/asoimg/jupiter0215a.JPG
http://www.arksky.org/asoimg/jupiter0215b.jpg
and (black and white CCD/low res)
http://www.arksky.org/asoimg/jupiter0215b1.jpg
you can see that BA is positioned not exactly coincident with the
central
minor axis of the GRS at this time,
still slightly west of a true longitudinal alignment.
NOTE that it appears quite evident at least at this time that BA
may well pass unscathed south of the limits of the GRS; at this time they are
well maintaining their "independent status."
However, it does appear that some resulting effects of this
interaction are occurring well preceding (east) of the GRS within the STrZ,
with several oval feature evident just ahead of the spot as well as a newly
emerging STrZ streak located in a latitude coincident with the major axis of
the GRS. The area of great intensity following
BA is become quite dark as well, with many small transient white spot features
emerging in areas southwest of BA.

@ . . . . . . IMPORTANT DEVELOPMENTS
NEAR BA/GRS -
"jupiter0215a" - Seeing
good; note the beautiful festoon activity within the NEZ and the very dark NEW
gray streak/bar on the s. edge of the NEB, just on the CM! Of most importance is the incredibly rapid
development of features and transient activity just preceding the GRS in the
STrZ. Note evidence of another less
distinct oval of the same latitude as BA just pr. BA and slightly pr. and south
of the GRS; several smaller white features are also identifiable within this
immediate area. VERY interesting
interaction just N. of the GRS with the SEBs component which appears to wrap
"under" the perimeter of the spot.
"jupiter0215b" - Seeing fair. The intense dusky activity and features pr. the GRS are seen in
this image. Note very large and dark
gray equatorial festoon emanating from the dark bar/streak on the NEBs edge.

Hello to all - with heavy cirrus

Note the pinkish tinge to oval BA and
how it has grown in recent days, particularly over the course of the past 10
days. Also note the string ofsmall
white ovals/spots immediately following BA.
There is much activity surrounding the GRS as can be seen in this image,
and likely due to current interactions as BA is now nearly central in
longitudinal placement to the GRS.
I expect a rapid change in motion for BA within only days, and am
detecting a slight acceleration of it over its previous rate at this time.
Beautiful rift forming very rapidly in the North Equatorial Belt....
