Venus-Uranus-Mars—Two Conjunctions

Conjunctions of Venus, Mars and Uranus - 11 March 2015
Conjunctions of Venus, Mars and Uranus – 11 March 2015

Object Name (Venus, Mars, Uranus)
Object Type (Planet conjunctions)
Location (Artignosc-sur-Verdon – Provence, France)
Date (11/03/2015)
Media (graphite pencil, watercolour pencils, white watercolour paper,

I always have issue to find Uranus, without GoTo, it’s not so easy…and I don’t like facility…
Thinks are moving in our planet system. It’s why “planetos” in Greek means “vagabond”.
So I use the opportunity of this double conjunction just a week from each other to find Uranus and its so nice colour.
The Venus-Uranus separation was 5.2’ Venus was 10’000 more brilliant than Uranus, while the separation between Mars and Uranus, one week later was 16.25’
The faint K star between Mars and Uranus is HIP 4325 mag=9.5, so no Uranus satellites were visible with my material.

I sketch the two fields on white watercolour paper with inverted method using a chromatic wheel, orange for Venus, blue for Mars and crimson red for Uranus then I just have to invert the two sketches after scanning. The deal is to manage the colour values in inverted mode.

Clear sky to you all, and for some of you I wish you a nice eclipse on Mart 20.

Object Name (Uranus with moons)
Object Type (Planet and satellites)

Media (graphite pencil, and inverted watercolor on white paper, for the inversion)
That’s maybe because I like to use this great telescope, or it’s because I like challenges but,… it’s certainly not the best optical combination for this observation.
On 11 December, I finally found a corner of pure sky above the 24-inch reflector made by Olivier Planchon. To observe Uranus, the speed is definitely too high: f / 3.3 d, so we had to use very short focal EP to reach the useful magnification (Nagler 3.7 and 2.5) !.
If you look at my watercolor you can see a somewhat elongated comet hair that diffuse around the planet, that’s exactly how we see the planet area in the field, this is probably linked to a not 100% perfect collimation, but still. I get the impression that the work of collimation facing these big tubes, it is not a piece of cake.
Anyway, we can say two things:
1- We observed three of the Uranus satellites: Oberon, Titania and Ariel, this last one being a bit lost in the lights of the planet
2- the disk of the planet was not uniform as seen in a small telescope or some photos. It’s very difficult to confirm, but a diffuse zone clearer was observed in the upper atmosphere of Uranus, is that an artifact, I do not know? Anyway the main direction of the area is not in the direction of the cloud bands of Uranus.

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!

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!


Jupiter and Uranus Together

Jupiter and Uranus Together

Sketch and Details by Carlos E. Hernandez

I was able to view Jupiter and Uranus tonight (September 18, 2010 at 01:30 U.T.) under better atmospheric (seeing) conditions while using my Oberwerk 11 x 56 mm binoculars. We had just had a rain storm and the skies cleared beautifully with relatively faint stars (5m+) visible overhead. Jupiter appeared sharp in the binocular field and now all four of the Galilean satellites were visible. Uranus was visible near Jupiter and was now 48.9 arc-minutes (0.82 degrees) apart from it. The other stars identified in my previous observation were also visible but now were now clearer. I hope that others were able to view this pairing as well.

Patience is it’s Own Reward

Uranus Observation on July 29, 2010

Sketch and Details by Carlos E. Hernandez

I made an observation of Uranus on July 29, 2010 (05:30 U.T.) using my 9-inch (23-cm) F.13.5 Maksutov-Cassegrain (310x). The small pastel green (or teal) disk of Uranus was very sharp at even higher magnification but I chose to examine it at moderate amplification. The center of the disk appeared to exhibit a faint dusky to dull (4-5/10) bar with a brightening (6-7/10) over the polar regions. These faint albedo features were not easy to detect but patience at the eyepiece allowed me to detect them. I hope that everyone gets a look at the Georgian planet.

Moon over Armagh

Moon over Armagh
Moon over Armagh on Christmas Eve
Sketch and Details by Miruna Popescu

This painting depicts how the southern sky looks on 24 December 2009 at 5.30 pm, when the Moon’s phase reaches first quarter. The next brightest celestial object at this time is the planet Jupiter, which this year is the “Christmas Star” for the Royal School, Armagh. Jupiter is seen here just before it disappears behind the school. The painting shows stars in Pisces, Pegasus, Aquarius and other constellations, and the location of the planet Uranus (visible through a telescope) about a third of the way from the Moon to Jupiter. Uranus was found in 1781 (seven years after the old building of the Royal School was completed) by the astronomer and musician William Herschel, the discovery constituting the first identification of a planet since ancient times and earning Herschel the post of King’s astronomer from George III.

In 1609, the year after the founding of the Royal School, Galileo Galilei used an early telescope to map the Moon and discover satellites of Jupiter. To mark the 400th anniversary of Galileo’s first use of the telescope to observe the sky, 2009 is being celebrated worldwide as the International Year of Astronomy.

Dr Miruna Popescu from Armagh Observatory is the coordinator for the International Year of Astronomy 2009 in Ireland.
