雲を透しての撮像で、光量不足のためフィルターを外して撮像しても、やっとであった。

I was finally able to make another observation of Jupiter tonight (11:30 PM,05/22/07). I was able to note a good amount of detail even though the seeing was initially erratic,but eventually improved. The region between the South Equatorial belt (SEB,Equatorial Zone (EZ),and North Equatorial belt (NEB) was very active. A prominent blue festoon was visible on the CM over the southern border of the SEB. I hope that you like it.
Date (U.T.): May 23,2007
Time (U.T.): 03:30
L1 308.7,L2 214.4,L3 095.6
Instrument: 9-inch (23-cm) F/13.5 Maksutov-Cassegrain
Magnification: 258x
Filters: None
Seeing (1-10): 4-6,Antoniadi (I-V): III
Transparency (1-6): 3
Notes:
South Polar Region (SPR): Appeared dark to dull (3-5/10) and mottled.
South Temperate Zone (STZ): Appeared thin,bright (7/10) and erratic.
South Temperate Belt (STB): Appeared dark to dusky (3-4/10) and broad.
South Tropical Zone (STrZ): Appeared bright to shaded (6-7/10) and no detail was visible within it.
South Equatorial Belt (SEB): Appeared dark to dusky (3-4/10) and bisected. The southern component was intact and broader.
The northern component was thin and a dark (3/10) condensation was noted on the CM.
Equatorial Zone (EZ): Appeared complex and containing dusky to dull (4-5/10) festoon projections,bright to very bright (7-8/10) ovals,
and shaded (6/10) sections.
North Equatorial Belt (NEB): Appeared dark to dusky (3-4/10) and broad. A prominent blue festoon was noted along it's southern border
on the CM. A thin,bright (7/10) rift was noted within it. A thin,dusky (4/10) belt (or band) was noted north of the northern border.
North Tropical Zone (NTrZ): Appeared bright (7/10) with the thin NEB- N belt (or band) over it's southern portion.
North Polar Region (NPR): Appeared dark to dull (3-5/10) and mottled.

Here is an extensive set of images obtained on the morning of May 23 in
unusually good seeing for 17 deg. alt.
The IR-R images and the 01:54 R image are in particular quite detailed.
The region of the new SEB outbreak is captured in the later images. In the
second colour composite,the S equatorial disturbance is seen as a white spot in
the SEB two-thirds of the way across,and S tropical disturbance 2 follows this
as a dark projection S of it.
In the first colour composite,where the GRS is central,the oval in the NNTB,
almost level with it,is seen as slightly pink.
Also,not to be overlooked,the fact that we no longer have a traditional bright
EqZ at all. The remaining light part is to the S,where it exists at all,but,
in the higher longitudes imaged here,that is also disrupted.
Unfortunately there are also a few artificial spots in the images due to dirt on
the chip,in in the latitudes of the GRS and NPR.

Here are the first Jupiter images from the latest trip from which i returned a couple of days ago. Weather was mostly excellent, but had some deterioration near the end as the hurricane season kicked off.
I've attached links to an RGB sequence as well as a slightly more contrasted G image for nice visualisation of the smaller details. Image data/info is found below the mail footer.
Many more images to come in the weeks ahead....
