Greetings all!
Attached is an observation made of Jupiter and its satellites on 2013 January 3rd. I have to say,
it was the most remarkable evening I have ever experinced in my observing career!
We had a sudden clearing at 2150UT,and the sky became very transparent.
Not only that,the seeing was exceptional- indeed I don't think I've seen conditions as steady as this,
Jupiter was without any distortion or quiver for many many minutes at a time.
I made two drawings of Jupiter. Interestingly,the GRS no longer seems to be touching the StropB
which now appears as a very dark brown. The spot just near to the GRS also appears to be apart of the belt.
Oval BA seemed to contain more orange colour than the GRS.
The region fol the GRS in the SEB showed a mass of delicate white regions spearated by fine grey lines.
A number of festoons present in the EZ,and what looks like a dark barge was present
in the NEBn by the time of the second drawing.
Perhaps the most interesting was the satellites. I examined both Io and Ganymede at x400.
Io remained featureless throughout the observation,but I was stunned to see some very subtle shading on Ganymede,
what appeared to be a brighter region at the top,and a darker region at the bottom.
No structure,just subtle shadings.
I had hoped to do some filter work- in particular I wanted to examine the planet and satellites
in W#25A and W#80A but the clouds came up again rapidly at 2316UT and
I was unable to continue further. Oh for another night like that!

For a long long time (exactly one year) I don't send anymore of
planetary images because my personal problems (at least a surgery on
my right meniscus) and the renovation of our new house and my
observing astronomical site !
So,these are the first captured sessions of Jupiter from last january
1st 2012 ! My new location is near to close city centre too,and I'm
building my personal scope-dome observatory.
Seeing wasn't great,however it was about 5 to 6 /10 (plenty). These
Jupiter images shows the transit of Io (and its shadow) and the shadow
of Ganymede: the session was characterized by the continuous passage
of clouds,but I was able to capture these moments in particulary;
note the Oval BA away from the GRS which has a reddish color; the GRS
seems to have some sort of eyebrows (the SEBn area inside which is
placed).

A rare double shadow transit occurred on this night.
Seeing was only good toward the very end when this was captured.
The Moons were taken and processed separately.
It was a lovely sight in the eyepiece as the shadows left the disk.
Oval BA is also nicely visible as is the new south equatorial disturbance.
