Jupiter – 1 April 2015

Hi,

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.

Best regards.
Roberto.

Tango Between Two Jupitermoons

Europa and Ganymede
Europa and Ganymede

Dear ASOD

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!

Jupiter and Europa – November 29, 2013

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.

Jupiter – Triple Shadow Transit – October 12, 2013

Hi all,

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.

Saturn and Enceladus

Saturn and Enceladus- June 20, 2013
Saturn and Enceladus – June 20, 2013

I have not sketched Saturn this go around until now because of extremely poor weather so far this year. On Wednesday evening the atmosphere cooperated and I had a scope outside cooling down. I did not have access to any Saturn templates because of a computer crash. So I took out my old mechanical drawing equipment and made an ellipse of the approximate eccentricity of Saturn’s rings and sketched from there. It’s a bit crude but reasonably close to the view. Seeing was good and the atmosphere was transparent. I was able to see Mimas but it was just beyond the way I framed the sketch for posting. Enceladus was about 12th magnitude.

Notes:

Horizontal image investment because used diagonal mirror.

The predominant color on the planet is a very pale yellow (at other times showed an intense golden) contrasting with some greyish belts with ill-defined irregularities. It clearly shows the shadow of the planet on the rings.

The Cassini Division shows a high contrast and a black is intense and well defined.

I could clearly see the satellites Titan, Rhea, Dione. Tethys only very weakly.

Enceladus, I’d be on the limit of this equip, but It was not possible to distinguish. Mimas is beyond the scope of this opening.

Hello friends of the planets,

yesterday the weather was the first time very good. And the night was great. After many deep-sky-impressions I waited for Saturn and the air was as good as possible.

It is my first Saturn sketch in 2013 and I sketched the ring-planet without any helps. So I need about 20 minutes for the ring system only. It is very hard to sketch it quite well and it needs little work in the warm living room after the session. 😉

Io Transit in the Mist

Io Transit of Jupiter - November 18, 2012
Io Transit of Jupiter - November 18, 2012

Object Name: Jupiter
Object Type : Transit of Io
Location: Wilp, The Netherlands
Date: November 18, 2012
Media: White paper, graphite pencil, Photoshop

Last night a nice transit of Jupiter’s moon Io was visible from Europe. The transit of Io (and its shadow) started when Jupiter was still very low in the East, but it rose very quickly. Seeing conditions improved and more details became visible. It was a very foggy evening in the Netherlands, but Jupiter just peeked through the mist. The tiny black dot of Io’s shadow was immediately visible. The moon itself became visible when it moved more to the limb of the planet (due to the edge darkening of Jupiter).
I made a small (2″ diameter), quick sketch of the view through my 16″ Dobson at 225x. I later enhanced the contrast and colorised it a bit with Photoshop, to match the actual view through the eyepiece as much as possible.

(It is one of my first sketches of Jupiter, so I sketched it a bit too small. Next time I’ll try to sketch a bigger planet, maybe 4″.)

Clear Skies,

Jupiter and Io - November 18, 2012

Dear reader,

Last night (November 18) Io was transiting Jupiter. I made a sketch of the event from 19:30 – 20:00 UT. The telescope used was an Astrosib 250 mm f/8 Ritchey-Chretien, with magnifications between 91x and 370x (Vixen LVW 13 & 22 mm + Barlow). The sketch has been made behind the telescope and drawn with a 3B graphite pencil. However, I played with it in Photoshop (CS4) to mimic the seeing.

Hey,

I send my sketch of the “Occultation of Jupiter”

Sketch shows a moment of Jupiter by the Moon Cloak and umbrella immunity telescope eyepiece at 120x magnification. God heard my prayers! Despite the terrible weather the moon emerged from behind the clouds. The view was magnificent. Emotions reached its zenith. Sketch was made before the moon covered the planet. Unfortunately I did not see the moons of Jupiter as the light clouds hamper perception. I hope you managed to show this phenomenon :))
In addition, the nature of the country lent incredible experience.

Object Name: Saturn
Object Type: Planet
Location: Deventer, The Netherlands
Date: May 13, 2012
Media: Pastel pencils on black paper

Last night I wanted to make a sketch of Saturn, mostly to capture as much moons as possible through my old 75mm f/15 Polarex/Unitron refractor. After 45 minutes of sketching at 200x with pastel pencils on black paper, Saturn was pretty much done (although I found it surprisingly difficult to draw a good ellipse for the rings), and just when I added the easily visble Titan, I heard some droplets on the trees next to me and felt something on my head: RAIN! I immediately covered the pastel sketch witch my hand and rushed inside my shed. After the sketch was save I pulled the telescope out of the rain. The most abrupt ending of a sketching session ever! I had completely missed the incoming clouds while viewing through the eyepiece.

Anyway, both the sketch and the telescope survived. Sadly with only one moon observed: Titan.

Clear skies and kind regards,

Hello artists,allo.k. after the big dinner of this days? I started my sketch activity very good, I go to hill near my town and, with my refractor kenko 80mm 1000 of focal length, I have observed in first time Venus (very low and disturbed by turbulence), Moon and at the end Jupiter.
When i see in the scope made my shout: “Wow”!!
I see the transit of IO in front the giant and his shadow!! I’m very lucky!
I made with pen the first version of sketch, after i realized a copy with graphite pencil.
I hope to continue in this line for all 2012…

Dual Transit

Jupiter Europa Shadow Transit
Jupiter Europa Shadow Transit

On the night of Dec. 20, 2011 I managed to catch a tansit of the Great Red Spot on Jupiter with the shadow of the moon Europa also tranisting near the GRS. The telescope used was a 120mm refractor at 125x while observing in my suburban Orleans, Ontario, Canada backyard. The sketch was done at the eyepiece and later cleaned up in Paint Shop Pro. The colour was added with coloured pencils and pasted into the reversed scan of the original sketch.

Jupiter and Its Moons

Jupiter and Moons

Dear Asod,

I send you here the sketch made by my daughter, age of 6.

She likes coming out with me and watching the sunspots, the lunar craters and planets, but this was the very first time she sketched like the ‘big ones’. She has stood next to the telescope with a pencil and a notepad and examined the object very knowingly just like an adult does it. Finally she came out with this sketch, which was quite realistic. The moons are in their place and also she could see a few additional stars.

This is sketch of the Jupiter and one of his moons – Europa, which had a beautiful transit in the front of the Jupiter. I used an 8″ reflector with a 240x power. Seeing wasn’t so good as a few days ago, but it was livable and there wasn’t even one cloud on the sky. The Europa and her shadow was clearly visible, so I decided to made this sketch.

Media: graphite pencil on white paper, scanned then inverted and colors edited
Observer: Rodrigo Pasiani Costa

I spent that whole night observing the sky from backyard, and one of my targets was Saturn. Despite the clouds, the seeing and transparency were great, so I could see Saturn like never before (450x without any loss). Both the shadows of the rings on the globe and the shadows of the globe over the rings were clearly seen, splitting one another. The Cassini Division could be seen in both ends of the rings, but the difference in the outer ring color was not notable. A dark stripe crossed the planet, fading yet very remarkable. Another shy dark stripe intended to follow the first one, however was not able to cross the hole bright disc. Two of its moons were visible. In fact, Iapetus was probably visible too, however it was far away from the planet, and I missed it.
The next night it rained a lot, and I spent it doing something else. The following three nights the sky was clear again, and I could observe Saturn and its moons. I made this four sketches (in second picture) to show the dance of the moons around Saturn, all made at the same hour, during four days. Follow the sequence:
a) December 27, 2010
b) December 29, 2010
c) December 30, 2010
d) December 31, 2010
I hope you enjoy it, it was really pleasant to observe Saturn last summer.

Meeting of Jupiter and Uranus

Hey, and Happy New Year to all!!

It was very interesting to observe both planets, Jupiter and Uranus so close together as 31 arcmin.
I could see only one Jupiter moon to west in my 10 x 50 binocular.
The sky was very clean, 0 deg. C, and no wind or other interference.
I did not see the partial eclipse in the morning , but I enjoyed this conjunctione!

Best wishes from Per-Jonny Bremseth. More info on my sketch!

Three-element 2.5x Barlow (not a good option that night)
Turbulence: 3/5 (regular)
A fair wind lasted all night long. It was a hot summer, cloudless night. In the sketch, aligned, from left to right: Europa, Jupiter, Io, Ganimedes and Callisto. A star can be seen in the bottom (20 Psc), really similar to the Galilean Moons. Another star, very faint, tried to show some contrast over the glow of the planet. Few minutes later, Jupiter hide behind my house, escorted by its moons and the stars. So that’s what I saw that night, from my backyard, in a small town, struggling against the sodium lights of the city: a beautiful Jupiter, surrounded by its 4 greatest moons, and two stars. I tried all combinations of lenses, however the 10mm (without the barlow) produced the best image. I hope you enjoy it, new sketches of a nebulae, a galaxy and Saturn are coming soon.

P.S. If you are going to comment, please say to my friend Camila that my sketches aren’t that bad. Thank’s!

Clear skies to everybody, and a happy new year,
Rodrigo Pasiani Costa.

Comments:
It was a cloudy sunday night, it had rained for some days in a row, and it was my last hours on countryside. While I waited for the time to go to take the bus toward São Bernardo, my mother warned me: “The sky is clear now…” I grabbed my telescope and went downstairs, and there it was: a bright Jupiter rising over my neighbor’s house. I kept observing it for almost two hours, and I got some surprises. I wasn’t aware the giant planet had lost one of the equatorial stripes. I saw a bright spot, similar to the Red Spot, but in a different place and smaller. I decided to take some notes [after some researches, I think it’s the Oval BA]. Ten o’clock pm (local), it was time to take the bus. I ended my observation, a great brief night of observation.

Comments :

There is no better time than right now! As the summer parade of planets bid
farewell and disappear into the western horizon,(Venus,Mars & Saturn)
Jupiter steps up to the spotlight on the East side of town. Jupiter has an
ongoing list of activities happening on and off its surface. Physically, the
sheer size of its disk is expected to reach 50″ as it nears opposition on
the 20th of this month. As of the time of this sketch, it had a disk size of
49.7″. Although not as bright as Venus(-4.7), It’s pretty shiny for being
the only contender on the lonely Southeastern front of the night sky.

On its surface or close to its Jovian atmosphere, Jupiter was recently
recorded to have been struck by some sizeable bolides. Meteors that burst
into fireballs while getting pulled by the gravity of the gas giant. While I
did not notice any of those fireballs(would’ve been cool), I did notice
other features.Through the scope the most obvious is that Jupiter is
spinning with only one of the two major belts. Only the North Equatorial
Belt is clearly visible. Last spring, the South Equatorial Belt just
disappeared before our averted eyes. It’s believed to be hiding under a
thick blanket of ammonia clouds. Previous circumstances have shown that the
SEB will resurface sometime soon. For now, a slight grayish hue is all that
remains visible of the SEB ocassionally highlighted by darker shades of eddy
currents. The Great Red Spot is easy to ‘spot’ since the lack of the SEB
doesn’t mask it from view, it seems to ride adjacent to the South Temperate
Belt. The GRS is not alone, it was found to have an oval reddish storm about
half its size keeping company just South of its perimeter. Under steady sky
conditions, the designated ‘Oval BA’ or ‘Red Spot Jr” was barely discernible
to the Southwest of the GRS. A more pronounced white oval storm was embedded
and riding high on the westernmost edge of the NEB. For added effect, the
Galilean satellite Europa was just coming out of occultation on the Eastern
limb next to the North Temperate Belt.

From a different perspective, through the binoculars, Jupiter is not exactly
all alone. In the same field of view Uranus is not far away from its big
brother. During my observation both planets were a separated by less than 1
and 1/2 degrees. Uranus will also reach opposition hours later after
Jupiter. Uranus’ disk is very tiny in comparison with Jupiter but you can
still get a pastel lightgreen color out of it. I tried to locate with the
naked eye and had some slight success but I believe its because I knew where
to look. Other than that I think I would have a hard time picking it out-I
was in Surprise I have to admit, not exactly dark skies.

I hope you enjoyed this little report, wishing you all dark and clear skies!
