 This is a very nice shot with steady skies. Note the clarity of the dusky oval BA and the beautiful fine detail visible in the SEB zone following the GRS.

 Also note the development of perhaps a GRS "hollow" immediately fol. the GRS.

 NOTE:  there appears to be some type of "bridging" activity between the GRS and oval BA at this time; if you look carefully at this image you can see a dusky lane at the SW edge of the GRS extending to the NE edge of oval BA.

 Hi Antonio and Clay,

Many thanks for those images, and for pointing out the interesting changes in STropBand (detachment from GRS), the oval in it (methane-bright again), oval BA (outline varying as it encounters GRS), and NEB rifted region (new bright spots S of the barges).

 

 It is particularly interesting to compare your methane and visible images of Jan.10/11. The STropZ oval seems to be visibly reddish for the first time as well as methane-bright. And in oval BA it seems that the methane-bright anticyclonic oval is smaller than the visible oval, possibly restricted to the Sf. end - much as with oval BE did before the last merger - the hi-res compositing would be needed to be sure! (See attached selection from Antonio's images.)

 All the best,

 John H ROGERS

Correspondence to Maurizio per his excellent image of January 12. SHOWING DUPLICATE ovals at BA Yes.....that is Oval BA, the one which is set for an intersection/merge/passing of the GRS on or about March 3; you CLEARLY have shown a good delineation here of the white oval BA into two components.

 This perhaps is due to current interactions of late as the two features near one-another.

 This is a very important development and one that you should report as such to John Rogers and the others. I am taking the liberty of converting the last bitmap you sent to me into jpg and forwarding it to my Jupiter list....this is a VERY significant development that needs to be studied and watched carefully over the next few days and weeks.

Thanks again, Maurizio.  This is what makes dedicated observation and monitoring of Jupiter exciting and rewarding.

  Hi Clay, Still haven't got the hang of the Yahoo thing, but I send this shot from two nights ago for your inspection.  Looks like there are two ovals totally stacked up on top of each other, just following the GRS.  Let me know what you think.   Best,

Maurizio

Subject: The Extending Diagonal NEB "rift"

 

I have just received an excellent confirming image from Frank J Melillo on January 19 which shows not only the interesting proximity of oval BA to the GRS, but also the large and distinct diagonal (SE toward NW) RIFT that is bisecting the NEB at this time beginning at about Long. II 70 degrees and extending all the way to the very intense dark barge B-4 at about Long II. 160 degrees.

This rift is a relatively newly-intensified feature that we began noting in early January, but of late has become very pronounced and well-delineated; in fact it has now extended from its pr. end (near 70d II) and seemingly merged with that extending eastward from the barge B-4.

 This "rift" is expanding EASTWARD at a very rapid clip, that appearing to match the acceleration of the recently-merged NEB barge B-3 which we have calculated at a period of 9h 55m 21.9s.

 I think that this acceleration is a very important event that bears careful watching, particularly in regard to the NEB barges at the pr. end of this feature which are rotating at present in a consistent System II current.

 In addition, the NEB diagonal rift is increasing its latitudinal separation or "girth" in recent weeks, and there is clear evidence, particularly on the pr. end (see ASO images:

http://www.arksky.org/asoimg/jupiter0111b.jpg(Jan. 11)

and

http://www.arksky.org/asoimg/jupiter0109c.jpg(Jan. 9)

for the pr. end extension of this activity INTO the far north NEZ. At the fol. end of this

(http://www.arksky.org/asoimg/jupiter0112d.jpg)

you can clearly see an extension from barge B-4 likewise extending into the NEZ, right at the point of convergence of B-4 and this diagonal NEB rift.

 We are seeing some direct reactive activity from feature convergence and interaction throughout this span and the activity appears to be changing daily.

Subject: ALERT - Wonderful new activity in NEB - ASO Jupiter Patrol Jan. 20

 

Notice - in the image just acquired at the ASO, note the feature associated near barges B-5 and B-6, located within the southern edge of the NEB and within the NEZ; this is a remarkably developing area characterized by a compression of the girth of the NEB in latitude toward center of barge B-6 and the development of NEZ activity to its south.

 Those not receiving this image note that it is posted on the ASO Image Archives under the dates January 20 (all patrol images for this date) or by:

Final send for Jan. 20.  Seeing slightly improved, with much activity noted along the northern edge of the NEB. Very nice bridging developing between STrZ streak and the s. edge of the SEB; also note the very interesting activity and change in the northern edge of the NEB and into the NTrZ.

 Two images concentrating on the very active regions near the GRS and oval BA as well as the turbulent NEB. Seeing excellent in "jupiter 0122b"; note wonderful detail in southern hemisphere; oval BA is now distinctly two sections in N/S diagonal split. GRS measured at center = 74.7d II / 156.3d III. Note NEB diagonal rift emanating near barge B-2/B-3.

Subject: NOTE: ASO Jupiter Patrol - Is BA overriding the GRS at this time???

NOTICE:  please see attached image "jupiter0122c"

http://www.arksky.org/asoimg/jupiter0122c.jpg

 

and carefully note that it now appears clearly that oval BA is overriding the perimeter of the GRS on its SW edge!
