Conjunction of the Moon, Venus and Jupiter
Sketch and Details by Carlos E. Hernandez

I made a naked eye observation of the Waxing Crescent Moon (3.76 days old), Venus, and Jupiter over the southwestern sky on December 1, 2008 (22:45 U.T.). The trio was paired between a pair of trees and pastel orange clouds. It was a very impressive sight. I hope that others were able to view it as well.

That Rare Phenomenon

Moon Venus Occultation

The Moon Occults Venus
Sketch and Details by Giorgio Bonacorsi

Hi astronomy sketchers,all o.k.? Today I made this sketch with very difficult (conditions) :Cold,strong wind and clouds and at the end,rain! But I don’t lost that rare phenomenon :Moon occulting Venus! The clouds covered the sky,the wind was very strong and cold, but I take my little Klevstov and made this sketch.I hope you like (it). I lost the Venus exit cause the clouds,but I see the planet at 6,30 p.m.for one second!
At next,clear sky.
Ciao,Giorgio.

Venus was shining like a million dollar jewel in the early evening sky.
The young moon hung low in milky blue atmosphere, giant Jupiter watched the
visually stunning occultation unfolding below.

As it got darker more and more detail became visible on the crescent moon.
Between finishing the Venus vanishing sketch and the reemergence of Venus
I put as much lunar detail as possible in the time and under the conditions as I could.

The view as Venus reappeared and once again sparkled like a diamond stuck on the moon was breathtaking .
I quickly place the planet as accurately as I could and then continued to enjoy the view
along with my fellow observers, Michael, Philip, Aubrey, and Keith, awesome afternoon.

Captivating Conjunction

Moon venus and Jupiter

Moon, Venus and Jupiter Conjuction
By Carlos E. Hernandez

Moon, Venus, and Jupiter

On February 5, 2008 (11:35 U.T.) I was able to view a very thin Waning Crescent Moon (27.9 days old) visible floating above (~5 degrees) a lavender cloud covered southeastern horizon. Venus was a very bright beacon (-3.97m) 12.2 degrees southwest of the Moon. Jupiter was a bright pastel orange-white star (~-1.87m) 4.0 degrees southwest of Venus. The southeast horizon exhibited pastel yellow to orange colors. I hope that others were able to view this pairing as well.

Shadow of the Goddess

transit of Venus

The transit of Venus June 4th, 2007
By Michael Rosolina

While listening to the McDonald Observatory’s StarDate, I was surprised to hear that
this week marks the 125th anniversary of the 1882 transit of Venus.  In my mind I
was transported back to June, 2004 eagerly anticipating the first Venus transit
since 1882.  No one living at that time had ever seen such an event.

The transit would be nearing its end when the Sun rose at my location so I set up my
small, portable Astroscan telescope equipped with a homemade white light filter on
the mountaintop behind my home.  I wanted my wife to see this rare event too, so I
lured her out by saying I needed her to watch my back for bears (not entirely
untrue–it was mating season and the black bears were very active).

As the Sun rose, we were completely enveloped in a cloud but soon the mist thinned
and we could see the small black dot against the solar disk with the unaided eye.
As conditions improved, we employed filters on the scope and on a pair of 10×50
binoculars to track the progress of Venus towards the Sun’s limb.

During egress, I was fortunate to detect the aureole created by the planet’s
atmosphere.  This halo was first seen during the 1761 transit by Russian scientist
Mikhail Lomonosov, who rightly concluded that Venus had an atmosphere.  The egress
created some interesting contrast effects which I have tried to render as I saw
them.

I later discovered that there was indeed a small sunspot group near the Sun’s
central meridian, but I could not see it because of the poor transparency.

The sketch was done in the field with 2B and HB graphite pencils on Strathmore
paper.  I used a 4 inch template for the Sun and a penny to make the template for
the inset.

Seeing the transit was a peak experience for me (my wife was glued to the binoculars
through the whole thing, too).  It was also very gratifying to see how the event
brought the global amateur astronomy community together as we shared sketches and
images via the Internet.

The next Transit of Venus will be June 6th, 2012.  Clear skies to all in 2012–there
won’t be another transit for over a hundred years.

A Brilliant Irony

Venus

Venus
Terrestrial Planet

It is somewhat ironic that the most brilliant planet in the sky is also the most challenging to observe. On 30 September 2007 Venus appears as a dazzling crescent (32% illuminated) in the morning sky, 42° west of the Sun and shining at magnitude –4.7.

This observation was made during morning twilight and the white cloud-tops of Venus displayed a fair amount of subtle, dusky shading, seemingly in a series of roughly parallel arcs curving northward. The shadings were most prominent toward the terminator, while the polar-regions were quite bright, particularly the southern cusp. In spite of the atmospheric subtlety, I found the observation of the large Venusian disk quite relaxing and relatively easy compared to the previous observation of the tiny Martian disk.

The Mysterious Terrestrial Planet

Venus 2007

  In the 1950’s when I was a youngster, Venus was believed to be Earth-like not only
in size but in atmospheric conditions as well.  Today it is known that Venus has
the hottest surface temperature of all the planets (457°C on average) and a high
pressure atmosphere of carbon dioxide and sulfuric acid. Venus is always shrouded
in clouds but its phase change and albedo features can be seen with a telescope.
The late spring and summer of 2007 have provided northern observers a great
opportunity to observe Venus in the west just after sunset. Within the week Venus
will reach inferior conjunction and begin to switch over to the morning sky as it
races past earth. Currently Venus is a thin crescent only 44 million km. from
earth and subtending an angular size of nearly 58 seconds of arc. Presently the
planet is too close in alignment with the sun for safe daytime observing but
beginning in September it will rise before the sun in the morning. The 4 drawings
above were made when  Venus was between 103 and 51 million km from the Earth.
The first drawing was made with an 18” Newtonian telescope at 381x and the other
three were made with a 10” Newtonian at magnifications between 161x and 241x.
Deep violet, red and polarizing filters were used to bring out the albedo cloud features.

Gibbous Goddess

Venus 

If you live in the temperate latitudes of the northern hemisphere, you’ve probably
noticed brilliant Venus high in the west at twilight–indeed, it’s hard to miss.
Apart from the phase, little detail is normally visible in the cloudtops of Venus,
due to the glare and low altitude of our “sister planet”.

This year presents the observer with a very favorable apparition because Venus
reaches greatest eastern elongation near the spring equinox.  If an observer uses
filters and gets out during early twilight (or even before sunset) while the planet
is still above the atmospheric murk on the horizon,  subtle detail can be seen on
Venus.

Even though it is our closest neighbor (next to the Luna) and has been visited by
spacecraft, there is still much that is unknown about Venus.  Iti s a worthy target
for any observer, especially during a favorable apparition.

This sketch was made using a 2B and HB graphite pencil, black ink, and a loaded
stump.  The sketch was done from an eyepiece diagram based on an intensity scale
where 0.0 = darkest and 10.0 = brightest.
