This sketch of my favorite planet of the solar system, that day their moons aligned, the great red spot and below this, the shadow of Europe, the picture was very rewarding and enjoyed meeting observation, but since the city only allows this type comments, try to have a place for these events really impressive. The original sketch was reduced and adjusted as is the eyepiece.
I made a digital animation in GIMP of a partial eclipse of Europa by Ganymede (27%). During the event I saw clearly a “division” between the two moons but it was impossible to tell which moon was before the other. Because I couldn’t detect any color difference between the two moons I guess the “division” was an optical illusion due to the 8-figure. Hope you like it!
On Friday evening after setting up to observe, I could see sky conditions would be better than average for this time of year( late fall).
When Jupiter climbed to more than 60 degrees above the horizon, I realized that this would be the night to make a first sketch of Jupiter for the season.
The GRS was redder than last season especially in its center and was well set apart from both the South Tropical Zone and South Equatorial Belt. Europa had just emerged from behind the North Tropical Zone on the following side of the planet. A couple of festoons could be clearly seen in the Equatorial Zone emerging from the North Equatorial Belt.
It was right at my tolerable cold temperature limit for sketching and I finished before needing to retreat indoors to warm up.
On a steady night of good seeing this is the time to give Jupiter a look.

Comments: Attached is the glorious Jupiter, with its four Galilean moons, from left to right: Io, Europa, Callisto, Ganymede. Usually, Jupiter shows more details, but its way past its prime viewing conditions at Sun-Earth opposition. The sketch was done by pencil, as observed at 240x, sky around the planet turned negative after scanning. Jupiter colors were adjusted using Photoshop to resemble observable Jovian palette better.
I’m re-sending this email with appropriate subject,
On October 12th good weather allowed me to see the rare triple shadow transit on Jupiter, and in addition seeing was excellent. Callisto’s shadow was big and somewhat fuzzy, near the south pole, while Io’s and Europa’s were tiny and sharp, at both sides of the SEB. It was very interesting to see all three shadows move across the planet for one hour! The sketch corresponds approximately to the middle of the event.

Moon in corona and Jupiter in Conjunction (14-04-2013)
The lunar light diffracted by water drops, gave a beautifull spectacle of colored ring around the Moon just – like an aureole ! Near shone the the largest planet in the Solar System with his four Galilean moons!
Jupiter and Moons were also in small halos 😉
It was remarkable and unforgettable conjunction!

I send you here attached my sketch of Jupiter made on 5th November 2011. Although the seeing was not so good I was able to see fine details I have not seen before, so that was a lucky day. I have even seen the colour so I decided to make my sketch with colour pastel pencil.
Equipment used: 130/650 SW, 130x
Date: 4th November 2011
Location: Budapest, Hungary
Media: brown shades of pastel pencils used on white paper.
