Jupiter – Page 10 – Astronomy Sketch of the Day

Backyard Jupiter

Object Name: Jupiter
Object Type: planet
Location: Itajobi – SP – Brazil
Date: 2010, July 20th
Time: 04h30min – U.T.
Media: colored pencil on white paper, photographed with Sony Cybershot 4.1MP (Carls Zeiss lens), edited with Paint.
Telescope: reflecting 180mm f/D=6 (dobsonian)
Eyepieces: SP 32mm (34x); Plossl 10mm (108x); SP 6mm (180x)
Observer: Rodrigo Pasiani Costa
Extra information:
That was a cloudy, cold night – for us, Brazilian people – around 12ºC. I had just aligned my mirrors and wanted to test the collimation. After one hour observing the moon through dark clouds, I saw the best picture of Jupiter ever (through my telescope) that night. Even through the 32mm eyepiece I could see two dark stripes crossing the giant planet, which was surrounded by its four brighest moons. Through the 10mm I got my best view, like the sketch. The 6mm eyepiece showed a low-resolution, distorted image. No filter used. I’d like to thank to Gabriel Piani Luna da Silva, that helped me with the telescope that afternoon, and also lent his backyard that night. It was his first time observing Jupiter, and he got impressed. I couldn’t forget to thank his mother, who gave us a delicious cake that afternoon, while we were fixing the telescope mounting. This is my first Jupiter sketch, I hope you enjoy it.

Best regards and clear skies to everybody,

Jupiter Showing Off Its Spot

Sketch and Details by Serge Vieillard

At an Astronomy gathering (Astrociel Valdrôme 2010) to view the deep sky early in the night, the second part of the night became a time for pointing at planet Jupiter as the atmosphere settles down.
Serge writes: [roughly translated]
“Jupiter introduces a new aspect, with his well shaded off Northern equatorial belt, which further emphasizes the great red spot in a very original way. … four color drawing were made directly at the eyepiece of the 460mm telescope with some supplementation using the 600mm scope over two nights (August 11 and 12, 2010).”
Here are two of those sketches.

Dessin de Jupiter

Bonjour,

Je vous joins un dessin de Jupiter réalisé le matin du 28 juillet dernier.
J’ai eu la chance de profiter d’excellentes conditions qui m’ont permises de dessiner la géante gazeuse dans de bonnes conditions et celà jusqu’à l’aubePour celà j’ai utilisé mon télescope 180 à des grossissements allant de x196 à x360.
Le dessin a été fait aux crayons de couleur.

Amicalement

Christian Gros

Hello,

I join(contact) you a drawing of Jupiter realized in the morning of last July 28th.
I was lucky to take advantage of excellent conditions which allowed me to draw the gaseous giant in good conditions and celà until dawn! For celà I used my telescope 180 in going swellings of x196 in x360.
The drawing was made for coloured pencils.

Friendly

Earth, Moon and Jupiter Conjuction

Moon july 4th 2010.jpg
Object Name : Earth, Moon and Jupiter
Object Type : Solar System
Instrument Used : Naked Eye
Location :
Date : July 4th 2010
Time : 2:45am local
Conditions : seeing 3/6, no clouds, a little dew
Media : Created a field sketch of this scene in my observing journal with pen and ink. The next day, I sketched the view with pastel pencils and black paper.
Description: The evening’s observations are drawing to a close when I notice the outline of the trees in the distance. Is that ghostly outline caused by the light of a gibbous moon? Then I realize that civil twilight is only two hours away. The light in the east is not due to the moon – but due to the sun.

Jupiter – May 26, 2010
By Michael Rosolina

Hello,

I was happy to see Per-Johnny’s historical sketch of Jupiter and sorry that the King is too low for him to make a current observation. Veteran Jupiter observers report that the South Equatorial Belt (SEB) follows a cycle of disappearance and reappearance over the years.

I was fortunate to get an opportunity to see Jupiter during the present cycle of disappearance. The SEB isn’t completely gone–the northern component was faintly visible. Some say that the SEB doesn’t really go away, but rather is covered by the bright zonal clouds bordering it, but no one knows for sure.

What is certain is that Jupiter looks very different without the symmetry of the northern and southern belts. Hopefully, all who wish to will get a chance to see this visual phenomenon.

The sketch was done in the field with HB and 2B pencils on white copy paper. Other notes are with the sketch.

Best to all,

Michael Rosolina

Jupiter Has Lost a Stripe

Jupiter – May 23, 2010
By Jef De Wit

Everybody knows that even in a small telescope you can see on Jupiter two brown belts. However when you turn your telescope on the planet now, you will see only one stripe!

The South Equatorial Belt (SEB), twice as wide as Earth and more than twenty times as long, is not actually gone, but may be just hiding underneath some higher white clouds. The last time this happened was in 1993.

When Jupiter is visible from my garden, the Sun is already high up in the sky. It took me 15 minutes to find the planet. Searching an object (except the Sun, the Moon and Venus) with a Dobson in broad daylight isn’t an easy job! Once in the eyepiece I could even see Jupiter easily in the finderscope (9×50).

Jupiter in daylight seems like a ghost. You have the impression to look through the planet. The North Equatorial Belt (NEB) was easy to see. But I was never so happy I couldn’t find something (this doesn’t happen fast in astronomy!). The SEB was nowhere. I guess the thin line is the northern border of the SEB.

Some details are not like actual photos of Jupiter. I saw the South Polar Region (SPR) brighter than the region just north of it. The north side of Jupiter looked as white as the Equatorial Zone (EZ), but in reality it is much darker.

A Missing Belt

Jupiter with Missing Cloud Belt – 1990
Per-Jonny Bremseth

Hello!

I send you my sketch from 1990 of the planet Jupiter with missing south equatorial belt. Now, the last week the SEB have again disappeared, and great disturbances have made the southern part of the planet light.

My sketch shows a chaotic northern equatorial belt (NEB), with a great, white spot along it, and a light southern half!

I used crayons on black paper. The observation was made outside Trondheim city, Norway.

Jupiter is too low for me this time, so good luck to others!!

Best wishes from Per-Jonny Bremseth.

An Alignment of Giants

Jupiter-Neptune Conjunction
Sketch and Details by Jeff Young

This pairing nearly got the better of me: I forgot all about it on Sunday night and Monday evening started out cloudy. However, it cleared at about 7pm and I headed out to the observatory — only to find the pair behind clouds again by the time I had the scope pointed. But I stuck at it, and the clouds cleared just as the pair started to set. (In fact, the sketch was done looking through the empty branches of a tree on my horizon.)

HB pencil on 150gsm cartridge paper. Sketched through a 16” Mak-Cass at 110X from County Louth, Ireland. Scanned and inverted and colourized in Photoshop.

Into the Depths of the Solar System

Conjunction of the Moon, Jupiter and Neptune
Sketch and Details by Peter Mayhew

Object name: Moon, Jupiter, Neptune
Object type: Conjunction
Location: York, UK
Date: 21st December 2009

I had to cycle home from work especially quickly on the icy roads in time to sketch this solar system trio before they sank below the trees. The sketch spans about 5 degrees of sky, with the 5-day crescent moon at the bottom (north) and Neptune and Jupiter with the Galileans at top. I observed them all at 18:00 UT through my Skywatcher Skyliner 150mm f8 Dobsonian with a 25mm eyepiece, repositioning the scope several times to include them all, and had to do this in about ten minutes before they sank from sight. Later I tidied the sketch up (graphite pencil on white paper) and reversed the colours and added labels. The field of view spans the closest heavenly body to us, as well as the farthest planet and the largest planet and helps give a sense of scale to our solar system family.
