I've
already sent the Moon and Jupiter with the 100mm refractor from this
night. Here's the C-14 on Jupiter. It was cloudy around culmination so I imaged later. Seeing was very poor, with lots of
shape-changing, so I only took a short sequence of RGBIR. The results have
turned out surprisingly not too bad, particularly when the I
image is incorporated – a tribute to Emil Kraaikamp's Autostakkert.

Dear Masatsugu,
We also have had a white Christmas here--the first for a number of

a severe head cold and so am taking it easy now as much as I can.
I am just now finishing the editing

Dear Masatsugu,
I have been thinking about you, and it occurred to me that you might enjoy a
photo of your old friend Sam and his grandson Kieran. David and Angelique
picked an Irish name for their son, in spite of the fact
that the only Irish thing about us is that we like potato soup. My family
tree is English and American "tossed salad." I hope you like the
photo. My poet Robert Frost liked to say that the one sure thing about life is
that it goes on.
We had a pleasant Christmas. My wife made a big and delicious meal, and
relatives came to visit. I am still stuffed with the Christmas meal.

This was actually
quite a difficult scene to image, as the Moon is so much brighter than Jupiter,
and Jupiter itself is so much brighter than its moons. This image is a merger
of a short exposure recording the Moon and Jupiter (Jupiter's cloud belts are
just visible) and a long exposure recording Jupiter's moons. The relative
brightnesses of he Moon and Jupiter have not been
altered. The moons were "cut out" in Photoshop and could be
accurately placed on the other image because one of them is so close to the

¤·····Subject: Re: from bill sheehan text of essay
Received;
Dear
Bill, Reiichi, and Masatsugu,
Thank you - and before everything, I hope that you are enjoying a nice
Christmas !
First, there is something important to say I think. Even if at one point we
consider that classical Mars observations (drawings) are obsolete, this does
not mean by any way that the classical observers themselves, are obsolete.... !
I mean that you Bill, Masatsugu etc. you have a long
and deep experience of the planet that are still interesting for anyone interesed in the observation of Mars. The different essays
you have both published in CMO have not lost any value in that everyone can
share this experience (not to talk about your books Bill).
You will then note that the "scientific obsolescence" is also true
for modern CCD images ; it strikes more earth-based observations than a kind of
technic itself. The true question is, is it still
possible to make science on Mars from the Earth?, and
if I believe my experience at the EPSC, the answer looks to be no... as another example, over the last months I have been
participating to the redaction of an article that will be published next year
in "Experimental astronomy" ; the aim of the paper is to collect
every possible topics of cooperation between professionals and amateurs in
planetary science. Each chapter is led by a professional with co-redaction from
both amateurs and pros. Well, there is not even a chapter on Mars (the planets
considered are Venus, Jupiter, Saturn, Uranus and Neptune). While I do share
for example the scientific interest of some ideas worked by Masatsugu
(he has written about them recently in CMO) the amateur or earth-based size of
science looks to be lost among modern scientists.
However, I'm always advocating the fact that "pure" science is not
the only interesting level of knowledge. Modern scientific topics on Mars will
be inaccessible for most of us. But there will ever be people observing Mars
from the Earth and they will always need more or less basics information about
the planet. Among the thousands of people (and still growing) that image the
planet from the Earth, how many know everything about the clouds of Mars, the
evolution of cap, everything about what we are writing in CMO
? Very little I guess. My thoughts about the future of CMO/ISMO is that
the review must play a key role here. And I have many ideas. Describing by
detailed notes of observations the basic climate of the planet will assure at
least still 10 to 15 years of publication, and people are always pleased to see
that their images are useful for this (and there is a room for good drawings
here). Now this would be my role and I hope that others will bring different contributions
(this is already the case btw). Note that this level of information will not be
found elsewhere than in publications by ISMO, SAF, BAA etc. Magazines of
astronomy do not go as deep.
To say it shortly, the CMO/ISMO must play a center role of animation among
amateur Mars observations.
A last remark about personal equations of observation. Yes of course, CCD
observers have all their own equation bias (and it can be very quite a lot with
time). The advantage of CCD is that the personal equation of one observer is
perhaps more accessible to others (of course it's better here to have a
personal experience of CCD ).
If you have any remarks about all this...
Best wishes,
Christophe PELLIER (

FROM CASSINI FOR THE HOLIDAYS: A SPLENDOR SELDOM SEEN
Just in time for the holidays, NASA's Cassini
spacecraft, in orbit around Saturn for more than eight years now, has delivered
another glorious, backlit view of the planet Saturn and its rings.
On
The last time Cassini had such an unusual perspective
on Saturn and its rings, at sufficient distance and with sufficient time to
make a full system mosaic, occurred in September 2006 when it captured a
mosaic, processed to look like natural color, entitled "In Saturn's
Shadow-The Pale Blue Dot" (http://www.ciclops.org/view.php?id=2230). In that mosaic, planet Earth put in a special appearance, making
"In Saturn's Shadow" one of the most popular Cassini
images to date.
The mosaic being released today by the mission and the imaging team, in
celebration of the 2012 holiday season, does not contain Earth: Along with the
sun, our planet is hidden behind Saturn. However, it was taken when Cassini was closer to Saturn and therefore shows more
detail in the rings than the one taken in 2006.
The new mosaic, composed of 60 images taken in the violet, visible and near
infrared part of the spectrum and processed in false color, can be found at http://ciclops.org, http://saturn.jpl.nasa.gov and http://www.nasa.gov/cassini.
"Of all the many glorious images we have received from Saturn, none are
more strikingly unusual than those taken from Saturn's shadow," said
Carolyn Porco, Cassini's
imaging team lead based at the Space Science Institute in Boulder, Colo, "They unveil a rare splendor seldom seen
anywhere else in our solar system."

CHARITUM
MONTES: A CRATERED WINTER WONDERLAND
The high-resolution stereo camera on ESA's Mars
Express imaged the Charitum Montes region of the Red
Planet on 18 June, near to Gale crater and the Argyre
basin featured in our October and November image releases.
The brighter features, giving the image an ethereal winter-like feel in the
color images, are surfaces covered with seasonal carbon dioxide frost.
Charitum Montes are a large group of rugged mountains
extending over almost 1000 km and bounding the southernmost rim of the Argyre impact basin.
They can be seen from Earth through larger telescopes and were named by Eugène Michel Antoniadi
(1870-1944) in his 1929 work "La Planète
Mars."
The images in this release all show the region's old and highly-sculpted
terrain, pockmarked with many large craters, all of which have been
substantially filled in. The whole region is dusted with brighter carbon
dioxide frost.
Numerous smaller 'pedestal craters' can also be seen in the 3D and 2D images.
These are impact craters where the ejecta have formed
a higher relief above the surroundings. One striking example is visible on the
smooth plain to the lower right in the annotated image (Box A).
The ejecta surrounding pedestal craters form
erosion-resistant layers, meaning that the immediate vicinity around the crater
erodes more slowly than the surrounding terrain. The resistant ejecta layer is largely untouched, forming the pedestal.
Another well-preserved example of a pedestal feature surrounding an impact
crater can be seen within the large, old and heavily-degraded crater on the
lower-left side of the annotated image (Box B).
In the center of the 2D images and dominating the perspective images is a
crater some 50 km wide filled with thick sedimentary deposits.
These deposits appear to have been introduced through one of several breaches
in the northern crater rim (Box C in the annotated image).
Dendritic channels appear to emanate from a
completely filled-in crater in this region (Box D), at the periphery of the
large crater's northern edge.
Within the large crater, near to where the breach (C) in the crater wall
occurred, though unconnected to this event, we can also see a small dune field
(Box E).
A region of significant interest to scientists lies within the large crater
towards the top left of the first image (Box F). This crater shows a diverse
range of filling material, with layers of varying color and texture.
The uppermost layer appears to be bright and smooth, taking on the appearance
of a relatively thin blanket with some impact craters.
This layer interfaces with the underlying darker layer via some very sharply
defined edges, possibly as a result of erosion.
The underlying darker material has a much rougher and mottled appearance, and
planetary geologists are still studying possible causes.
To the left of the crater interior, another layer of sediments clearly sets
itself apart from the underlying strata, partly forming flat-topped structures
(Box G).
The complexity and diversity of some areas in this winter wonderland would
doubtless give Father Christmas a hard time in finding somewhere safe to land,
but images like these are giving planetary geologists yet another fascinating
region of the Red Planet to study.

Dear
Masatsugu,
I have fond memories of
I spent yesterday doing exercise stress tests of my heart, and the
results seemed favorable. I am now on Diltiazem,
which seems to be successful; my heart rate is now back to normal, after over a
year in which I was running Marathons by merely walking slowly.

Hi
Guys here are two more from the nice seeing on the 30th . Note the two
grey clouds near the GRS that appear to be "floating over" and
obscuring the dark "trail" below them.

Dear Reiichi,?
I
have merged by eyes the 2 images as well (reduced), but I encounter problems to
see the LRS that is very small ! ?;)
In any case, as it is anticyclonic, we now that it rotates clockwise (in north
hemisphere). Spots in NNTZ will all be anticyclonic
(zones only produce anticyclones) and so if we see neighbouring
spots rotate counterclockwise, this means that they belong either to the NNTB
or the N3TB... as cyclonic spots must belong to a belt.
Best wishes,

I have checked some
spacecraft Jupiter animations and got mixed up to find, in NNTZ, some
dark-fringed bright ovals rotate clockwise, while other ones do
counterclockwise!

Dear Christophe, all, the tiny red spot in Jovian
NNTZ shown on your excellent 29 Nov. images is very interesting. I could have
managed to stereoscopically fuse your two LRGB images taken at 22h24m and
23h29mGMT respectively(65 minutes interval!). With parallel stereo-freeviewing the small RS looks farther than NNTB and closer
than NNNTB；This means the RS goes
slower than NNTB and does faster than NNNTB；may have a
rotation period about one minute shorter than the System-II, and the little RS
itself may rotates counterclockwise like some roundish
features in northern higher latitudes including NNTZ.

Jupiter images 29 nov. 2012 with NNTZ LRS-2

Hi all,
Here some images taken under good seeing, showing the new red spot in NNTZ.
It's very small, hard to detect in colour, but as
bright in CH4 as its older sisters. Its colour is
luminous pink, this being due to a relatively high albedo
in long wavelengths. Unfortunately the UV image does not look good enough to
decide if it has the same dark albedo as
the other RS, but I believe so.
On the other hand, there are some strange dark CH4 spots in SEBn/EZs
is this the possible new SED ?

Dear Masatsugu,
I have written the first part of an essay considering the
question: what remains for the visual observer of Mars in an era of spacecraft
surveillance.
I hope you will publish it in two parts, and I will write the second part in
the near future.
Kind regards,

Hi
Guys we have had a run of three clear nights this week and tonight looks
like the fourth.
Here

to Jupiter imaging after visiting
I only managed to get
a single RGB run of 3 mins total (about 3500 frames
