After three more nights of horrible weather (18" rain and counting....) we have a fairly good night tonight, albeit not steady at all.  Nonetheless the giant planet is cooperating with some interesting views! (sure is diminishing in overall size!).....

Seeing poor.  Some nice detail seen in spite of poor seeing conditions. Note the very bright yellow oval in the NEZ just w. of the CM; this was quite pronounced on the CCTV during imaging. Very nice northward extension of NEBn activity into the NTrZ west of the CM with this activity seemingly increasing some over past weeks. Some distinct activity now beginning to emerge in the hitherto quiet SEZ, as seen west of the CM.

seeing poor to fair.  Some nice contrast features are seen; note the very nice gray small oval s. of the NEBs in the NEZ...slightly w. of CM. Distinctly blue-gray.  NEZ is continuing to exhibit some very pronounced increase in visible activity. Small white spot seen near CM in SSTC.

Well, after a complete drought of nights free of clouds, there finally was an opening early, but the seeing was very poor if not impossible....got a shot of the GRS approaching the CM and the "new" oval feature immediately to its south at this time.  It is appearing all the more like a true oval, albeit one without a distinct peripheral border such as BA exhibited early-on.

 Also note the very dark segment/recess of the SEBn which is immediately pr and north of the GRS pr. end.

 For those note receiving the image, it is on the Arkansas Sky Image Archives at:

 Seeing the worst possible; focusing nearly impossible for the image moving and undulating constantly.  However the very dark barge B-4 is seen in the NEB clearly.

We have had about four straight weeks of really bad seeing conditions and I am getting reports from throughout North America of similar poor conditions for planetary viewing/imaging. Odd circumstances to say the least!

Jupiter image from tonight under very bad seeing; disturbance just e. of CM is developing rapidly, and a distinct hint of red or pink vividly recorded.

Very clear skies but unsteady air; getting so low I am getting to within a day or two of losing Jupiter in twilight and/or the western side of my building....[!!]

 Seeing very bad and Jupiter low in evening twilight.  Much interesting dark activity just on the s. edge of the NEB into the NEZ; note large EX festoon emanating from NEBs and curving fol. into NEX, near the EB.

 NOTE the string of large and bright ovals within the NEZ which are suddenly intensifying in both brightness and number fol. the CM in this image.

 Activity in the NTrZ also noted just fol. the CM, with bridging festoons between the NEBn edge and NTB.

Seeing fair to poor; image taken in strong twilight/daylight against blue sky.  Note the wonderful bright oval activity within the NEZ and the strong activity within the NEB northern 1/2.  Twilight conditions precluded increase contrast of such vague areas, but they are shown fairly well in this image.  Areas pr. and fol. the GRS as well as to its south are quite placid at this time.

 GRS and its environs appear to be quite back to "normal" with little residual effects from the oval interaction activity of previous months.

 Dark central area of GRS is quite pronounced and relatively unchanged.
