Here
is my first Saturn image for this apparition, the sky was clear and relatively
stable this morning for the first time in months.
This
is also the first image with my new scope, using a 16" composite mirror
that cools much faster than my previous conical mirror, a Siebert 3x barlow and Grasshopper Express
camera from PGR.
Saturn shows an interesting belt toward the north (at the
top in this image) as well as a few harder-to-see storms at the mid-north
latitudes. regards,

Dear
all,
I
would like to wish you all a happy 2012. The year of the transit of Venus has
started now, and preparations for observing it are now well under way. But in
January and February our focus will be on another celestial object providing us
an unparalleled educational opportunity: the asteroid Eros.
New
video trailer for the transit of Venus
The
Transit of Venus is a new four-minute trailer written and directed by Chuck Bueter, with animation and video effects by Patrick McPike, Multimedia Artist and Technical Director at the
Adler Planetarium. The video summarises the history and significance of the
transit of Venus while preparing viewers for the June 5-6, 2012, spectacle.
Starting with Jeremiah Horrocks’ first sighting, the
story traces its value from early expeditions seeking to measure the size of
the solar system, to similarities with transits around distant stars being
detected by the Kepler spacecraft. In the background
you hear the original song Morning Star by the band Transit of Venus from

Three

As

Nick
Lomb was Curator of Astronomy at Sydney Observatory from 1979 to 2009, was leader of the observatory's 2004 transit of Venus
team and is now consultant astronomer for Sydney Observatory. He recently wrote
a new book about the transit: Transit of Venus. 1631 to the
Present (Powerhouse Publishing, 2011). Being the only author living at a
place where the entire transit will be visible, Nick has a lot of interesting
experiences to share with us.
Huw
James is leading the Venus Transit Expedition, an eight week educational
overland endeavour to the
Phone
app ready by the end of January ? available
in March
The
phone app for the transit of Venus will be ready by the end of January. Then,
after it has been approved by Apple, free versions for iOS
and Android will be available in March. I wish to thank all of those who
participated in the test runs for their valuable feedback!
The Eros
Parallax Project
In
history, two celestial events were observed all across the world to find the
size of the solar system: the transit of Venus in 1761/1769 and 1874/1882, and
the opposition of the asteroid Eros in 1901/1931. Coincidentally, both these
historical important phenomena happen again this very year, providing an
unparalleled opportunity for a unique astronomical outreach project. In 2012,
we will be able to measure the distance to the sun from observing the parallax
of Eros as well as from the duration of the transit of Venus, and compare the
two results with each other and with historical data, all in only a few months'
time. Like the transits of Venus, favourable oppositions of Eros are quite
rare: only every 37 or 44 years the asteroid approaches Earth close enough to
make accurate parallax measurements.
When
Eros is photographed simultaneously from two widely separated locations, the
position of the asteroid with respect to the background stars will be a little
different on the two pictures due to parallax. If the amount of parallax is
found, and the distance between the observes is known,
the distance to Eros can be computed using trigonometry.
The
Eros Parallax Project runs from January 28 to February 3. On each night you
make picture of Eros (either through a telescope or with a telephoto lens) at
7, 18 or 23 UT, depending on your location. Then, using free and online
software, you determine the celestial coordinates of Eros on your picture and
submit the data to our website. From the data submitted by all participants,
the distance to Eros can be deduced.
Participating
is easy: take a picture of Eros, analyse the image and submit your data to our
website. But is also has great educational value: all data and many pictures
will be available afterwards for class rooms to process the submitted figures
themselves. Next to enjoying the night sky, developing observing skills and
gain understanding of our solar system, students will act like professional
astronomers of the 1930s, giving them a sense of what actual scholarly work is
like.
For
further historical backgrounds and detailed instructions for participants, take

image derotation function:
http://astrosurf.com/delcroix/images/planches/j20120111-MDe.jpg
Please
note the bright white spot in methan absorption band
in the North polar area.
As
some people asked me, I made a comparison between images done with WinJupos
derotation function and the best of the individual images used for this
derotation, under each filter. The derotation images
have been further processed (by a simple gaussian
mask) to improve details while not rising the noise more than for the
individual images.
http://astrosurf.com/delcroix/images/planches/j20120111w-MDe.jpg
RGB,
R and IR clearly benefits from this processing, while the methane derotation image, even if showing the SSTB white spots, is
less resolved on the bright white spot.

I
had to struggle with this one. It was
clear when I turned on the scope to begin imaging but as soon as I had Mars centered in the field of view clouds began rolling in from
the south. I waited for a good hole in
the clouds and I finally got one about 30 minutes later. However, it wasn't quite big enough and the
about 80 percent of green frames and 60 percent of the blue frames were no
good. As a result the green and blue
images are not that good. I did manage
to squeeze out enough information from them to get reasonable color for the composite.
Hopefully I'll have some clearer nights later this week.

Seeing was very bad on Jan. 4 so I was only
able to capture an IR image. The seeing
on Jan. 7 was below average, but at least I was able to capture RGB as well as
IR images. I am also 
including
an animated gif of all the red frames I captured that night from 7:57UT to
9:11UT. The animation allows detail to
be visible which otherwise would be overlooked in a still image.
I
would also like to make a correction to the images I submitted for Oct. 31,
Dec. 2, Dec. 12, Dec. 18, Dec. 27, and Dec. 29.
All these images state that they were resized 300%. The image captions should state that they
were resized 225% instead. All the other
information in those images is correct.
I am therefore not re-submitting any of those images.

estimate of the Earth to Sun distance
Received: Thu 29 Dec 2011 04:34 JST
Dear
Masatsugu (and Randall, my experimental archaeologist) (I am also cc:ing Professor Gomez who is
cited below)
The last issue of the CMO/ISMO with its
discussion of phase angles was of interest in part I have recently been
immersing myself (for various reasons) in the long history of measurements in
astronomy, and revisited the treatise of Aristarchus “On the Sizes of the Sun
and Moon.” This is one of the most
remarkable documents of ancient astronomy but probably (I have now learned) was
not really Aristarchus’s own treatise but a somewhat garbled rehash by a
successor of Aristarchus (pseudo-Aristarchus).
You know that the angle that pseudo- Aristarchus published—87
degrees—for the angle between the exactly half Moon, the observer on Earth, and
the Sun was much too large, and has always seemed suspicious; so much so that I
have always doubted whether Aristarachus could have
measured anything at all. (Have you or
other readers of the CMO ever attempted to repeat Aristarchus’s method, and
just how well does it work, even when one is using a telescope? There are many complications, including
fixing the position of the brilliant Sun and also the exact position of the
terminator-line on the Moon which, of course, is not a smooth round ball but
very rough and irregular. I propose this
as a challenge to our friends who have long disputed the craters on Mars
controversy to turn to something else—similar, but not as emotionally
charged. How well does Aristarchus’
method actually work, even with modern instruments?)
In any case, Dennis Rawlins and Alberto Gomez
Gomez have recently argued—I think quite
convincingly—that Aristarchus probably arrived at the figure by an analysis of
the limits of resolution of the human eye.
The 87 degree figure would be the smallest angle that would have been
detectable to the human eye. Thus the
distance from the Earth to the Sun—19 times that of the Moon—should be regarded
as a lower limit. Best,
Bill SHEEHAN (MN)

Dear
Professor Debarbat,
Forgive my use of English; I am writing to you at the suggestion
of James Lequeux.
I am a researcher in the history of
astronomy who will be visiting Paris (including the Observatoire)
in February--probably arriving about the 16th or so--and would like to if
possible pay a visit to Juvisy Observatory again (I was there in 2009 for the
International meeting of Mars Observers, but at that time the 9-inch telescope
had not yet been refurbished, which I understand it has been since last month
sometime). Professor Lequeux
has also expressed an interest in visiting the site, if this can be
arranged.
Since
Mars is one of my chef d'oeuvres, I would also like to inquire about the
possibility of observing the planet with this historic telescope (it will be
about two weeks away from an aphelic opposition).
When I toured Juvisy in the company of other
participants in the Mars conference in 2009, I went on a very interesting tour
of Flammarion's library collection given by Patrick Fuentes, who is of course
the great expert on Flammarion. Briefly
the three of us chatted (you, Patrick and I) chatted at Brera
Observatory in
I am also eager to hear of further progress
regarding your great Cassini biography.

where I understand there is a small Cassini museum.
Let me know whether it is possible to visit
Juvisy, and in any case I hope to meet you again when I am at the Observatoire.

Here is a set again taken under poor seeing. But in that
hard situation, the derotation tools of WinJupos brought a most welcome increase in SNR. Details

really like the derotation of single images. The

Dear
Friends and Colleagues,
The
holiday season is finally upon us! So,
today, in celebration of this beloved time of year and to mark Planet Earth's
northern winter solstice, the Cassini imaging team is releasing a small
collection of specially processed images of Saturn's largest and most colorful moon, Titan ... the only moon in the solar system
with a substantial atmosphere. A couple
of Saturn's stark, airless, icy moons also appears in
these scenes, seeming to dangle beside Titan's orange orb. The atmosphere of Titan is of great interest
because of its similarities to the atmosphere believed to exist long ago on the
early Earth.
Now
it's time. Go to ...
http://www.ciclops.org/view_event/167/
...
look under the tree, carefully pick only the packages
with the red bows, and you'll find your extraterrestrial surprises waiting
within.
(Also
find an image advisory that we released a short while ago attached to this
email.)
And
now, from all of us to all of you, a brimming sleigh-full of warm wishes that
your holidays are happy, peaceful, relaxing and safe.
Enjoy!

Dear Bill
ok for the
13th. It is a good idea trying to observe Mars those days!! We can either
arrange for an access to the 76 cm Great refractor (but that was used by Perrotin on later opposition if I'm not wrong). Or to the
50 cm, which is not the original instrument he first employed, but it is in the
same first dome. Or both ;-) !

Hi
Guys here are a few solar shots from a very low elevation of 13deg, but seeing
was not too bad at all. All the images are mosaics, I like jigsaw puzzles,
matching up the brightness, contrast and sharpness, in varying sky brightness
and cloud waftings, all adds to the fun. The limb
shot was double stack with the surface "inverted". I like the way the inversion "lifts"
the filaments up so they really do appear to be high above the surface, as
indeed they are.
