Received; 31 December 2012 at 10:41 JST

 

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.

 



Happy New Year.

Dear Masatsugu,
   We also have had a white Christmas here--the first for a number of years.
 I was enjoying cross-country skiing (my endurance had improved after I started the medication Diltiazem for the atrial fibrillation), but unfortunately have come down with a severe head cold and so am taking it easy now as much as I can.
 I am just now finishing the editing of the galley proofs of my brother's and my translation of James Lequeux's Le Verrier bio.
Yes,  I have received interesting comments on my essay Christophe and Reiichi, and am glad to see the beginning of a conversation.

 

I wish you and your wife and family the best for the coming year, and especially for you, good health.
 

Best,

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.

Best wishes to you and yours,

Received; 27 December 2012 at 09:56 JST

 

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 planet. The image is best viewed at full size.

 


 

Merry Christmas and clear skies in 2013!

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 (Nantes, FRANCE)

Seeing improved after culmination, as it seems to have often done recently, but oval BA was moving off, so I've included earlier and later R and RGB images. The IR image taken earlier proved quite sharp, so I have combined this with the RGB to give an L(IR)RGB image, which isn't colour-true, but is a bit different.

Dear Masatsugu and Reiichi,

   I appreciate the stimulating thoughts of Reiichi, and look forward to his essay, gthe Areoholic Reconnaissance Global Unionch  I think it offers a more optimistic assessment of the situation than my essay.  I believe that reading about Masatsugufs and Takashi Nakajimafs recent health problems forced me to consider the fact that they are not indestructible, and observers of that quality and longevity and dedication will be hard to find.

   I have attached a (slightly retouched) version of the essay—I wrote it so fast I didnft have a chance to proofread it, but have made some corrections so that, if possible, this version should be published rather than the earlier one.

   Perhaps for Part Two we could have a discussion of some of the points raised in the essay—or perhaps it would be Reiichifs essay that can carry this forward. 

   All the best, yours,

Seeing was slightly better early on the 16th than on previous nights. I started operating the Flea at a lower frame rate than before (20-30fps) and at about 50% gain. Result is fairly sharp but I'm getting the bright edge "ringing" effect that I was not getting with the Lumenera camera. I wonder why. Could just be the seeing.

 

The red streakiness and grey "toothiness" of the SEB markings is noticeable.

Comparing with my similar view from Dec 06, a subtle change I notice is that the disturbance in the NTB( N edge) just approaching the meridian has changed direction, in other words, the "spike" is pointing backwards rather than forwards.

and participate to Jupiter impact frequency evaluation project

 Received; 19 December 2012 at 14:52 JST

 

Dears,

In october this year Ricardo Hueso and his team (from Grupo de Ciencias Planetarias, Spain) launched two softwares aiming at detecting jovian impacts on planetary videos ( http://www.pvol.ehu.es/software/ ).
I pursued the development of one of them, DeTeCt (previously "dtc"), to improve its robustness, and add the following features:
    - Batch script launching detection on all acquisition files in all sub-directories in one click
    - Datation information in a log file for participation to impact frequency evaluation project and easy usage in winjupos (for measures/derotation, ...)
    - English and French comprehensive tutorial
    - FITs format support

Now with this version you can easily analyze all of your planetary videos for searching impacts, and by communicating your results (one single file) to us participate to a project for improving the evaluation of the  frequency of such events.

This software and the tutorial are available here : http://www.astrosurf.com/planetessaf/doc/dtc_tutorial_web.htm .
For any question or support, do not hesitate to contact me.
Looking forward seeing your results, good luck in your search for impacts!

I have a monochrome Flea 3 camera now, but haven't quite worked out the optimum settings for it. Here are some early results. I think the gain was too high, resulting in a ringing effect. Still, something useful might be got from these images.

 


The RGB is made from an RGBRGB sequence of 40s videos at 60fps. Io and its shadow are smeared by their orbital movement. Also provided is a single 40s red.

Dear Friends and Colleagues,
Of all the many glorious images we on Cassini have received from Saturn, none are more strikingly unusual than those we have taken from within Saturn's shadow. They unveil a rare splendor seldom seen anywhere else in our solar system.

Today, the Cassini imaging team is releasing one such image, actually a mosaic of sixty images, taken from Saturnfs shadow on
October 17, 2012 and processed in false color.

Go to
chttp://ciclops.org c to find a link to the new mosaic and a new Captain's Log. (Also, attached below is a press release that went out a moment ago..)

This glorious image is our special gift to you, the people of the world, in this holiday season that brings the year 2012 to a close.

I fervently hope it serves as a reminder that we humans, though troubled and warlike, are also the dreamers, thinkers, and explorers inhabiting one achingly beautiful planet, yearning for the sublime, and capable of the magnificent. We hope it reminds you to protect our planet with all your might and cherish the life it so naturally sustains.

Happy holidays to all!

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
Oct. 17, 2012, during its 174th orbit around the gas giant, Cassini was deliberately positioned within Saturn's shadow, a perfect location from which to look in the direction of the sun and take a backlit view of the rings and the dark side of the planet. Looking back towards the sun is a geometry referred to by planetary scientists as "high solar phase;" near the center of the target's shadow is the highest phase possible. This is a very scientifically advantageous and coveted viewing position as it can reveal details about both the rings and atmosphere that cannot be seen in lower solar phase.

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."

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in
Pasadena, manages the Cassini - Huygens mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team consists of scientists from the U.S., England, France and Germany. The imaging operations center is based at the Space Science Institute in Boulder, Colo.

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.

Hi all,
Some images from the 5-6, good seeing under the jetstream.

There looks to be a north temperate disturbance in the NTZ ; its preceding edge is slightly methane-bright.

Seeing was rather variable this night with some videos excellent, some no good at all. 

Selecting the best, the colour images are made from an RGBRGBR run (before midnight), and an RGBRGBRGB run after.

In a separate file, two particularly good reds from single (non-derotated) 1 minute videos, and in another file, the IR image, are given. 


(All my images are taken without any dispersion correction.)

I note the tiny red barge in the NTB(N), f the CM at 23:08 and p at 00:10. The EqZ can be rather beautiful.

Somehow every time I image Jupiter at the moment, I seem to get exactly the same longitude. At least it makes it easy to compare. This shows the same view as my image of the 1st. The merging barges in the NEB look more spread in longitude now. RGB and I (742nm) images.

Dear Masatsugu,
   I have fond memories of
Kyoto from my visit in 2004.
   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. 

Best,

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GThis means the RS goes slower than NNTB and does faster than NNNTBGmay 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.

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 ?

Hi Guys, Better seeing than of late. I have included the component channels too as the good seeing had produced quite a nice blue for a change.

Both the NEB and SEB are being increasingly overwhelmed by grey cloud.

Here is Jupiter from Saturday night. Seeing was average for here and jumpy.

A very similar view to that which I took on November 29, LRS-1 in the north and the merging barges in the NEB are the most prominent red features, plus there is a barge in the SEB following.

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

Here are the images from the 1st one i.e. the 28th of Nov.

Seeing was fair nothing special, but 29th and 30th were better, but short lived.

This morning saw unusually good seeing for this location. The diffraction pattern of Aldrebaran which I use to collimate with on screen looked almost perfect. Unfortunately there was cloud as Jupiter culminated at midnight, and it took a long time to move off. The beautiful filigree patterns in the cirrus illuminated by the moonlight, with a rainbow halo around the Moon, showed the stability of the high atmosphere. At 1am the cirrus patterns disappeared and the entire sky fugged over with a mist, but I kept monitoring Jupiter, and it cleared at 01:15 with seeing still good.

Here is oval BA rising and WS-Z near the centre of the disk. (Thanks John for the labelled map!)

Back to Jupiter imaging after visiting Australia for the eclipse and being ill since. 

I only managed to get a single RGB run of 3 mins total (about 3500 frames total) in on this occasion due to cloud, so detail is not great despite fair seeing. (The seeing this morning, the 30th, was exceptionally good).
