Hi all,

Good seeing on the 14th and excellent on the 15th. These images are taken with the new camera PLA-Mx as well as the Atmospheric dispersion corrector (ADC).

I really like the colorful aspect of the SEB on the 15th, optically enlarged by the presence of the little STrB. Will it complete the whole turn of the globe, like in 1990-91 ? The current aspect of the SEB/GRS reminds me quite a lot the aspect of the region after the 1990 SEB revival...

Best wishes,

¤········Subject: Transit of Venus Project Newsletter #2

Received: Sat 16 July 2011 16:23:05 JST

Dear all, A couple of new items have been added to the Transit of Venus Project's website during the last month: two exciting projects to join, and a new look for the local predictions of the 1639-2125 transits.

The sun's distance by simultaneous solar imaging

 Next to the classical method of Halley (timing the start and end of the transit from different locations), there's another method to determine the sun's distance from a transit of Venus: photographing the sun at the same moment from different locations. This procedure was out of the question in the 18th and 19th century because of difficulties with exact time keeping, but thanks to today's techniques it's now possible to conduct this method. Besides, it has a strong didactical value too, because the effect of parallax is directly perceivable and agrees with the way we experience parallax in daily life. Right now, a brief description of the method is given; an explanation of the evaluation of the results will follow shortly.


Observing the aureole effect

One of the more peculiar effects during ingress and egress is the illumination of Venus' atmosphere, and it keeps us surprising. Recently, Bill Sheehan and Jay Pasachoff showed that the first astronomer who observed this aureole effect in 1761 and attributed it to the atmosphere of Venus wasn't Michael Lomonosov, as was long thought. Using 2004 recordings of the aureole effect, Paolo Tanga investigated the effect and related its appearance to the structure of the planet's atmosphere. Tanga now invites you to make subsequent observations of the aureole during the 2012 transit of Venus in order to contribute to our understanding of the upper atmosphere of Venus.


Local predictions of the 1639-2125 transits

This is one of the key pages for your preparations for the 2012 transit of Venus. Where and when is the transit visible? What time are the contacts at my place? What part of the transit will I be able to see? You'll find an answer to these questions on our website. And there's more. You can also find the circumstances of all the transits back to the one Jeremiah Horrocks saw in December 1639, and look into the future up to the transit of December 2125. François Mignard formulated the algorithm for the computation of the contacts, and our web developer Rikkert Koppes managed to present all data in a user friendly and catchy design. Make sure to stop by!


I would like to thank all of you who have made a donation to fund the development of our phone app. But we're still short of our $15,000 goal. Please consider making or increasing your donation ? today! Without your support, we won't be able to start developing the app that will assist you and thousands of others in observing next year's transit.

All of the Active Regions in WL and HA. Most of the large proms including an impressive eruptive on the SE and granulation - I continue to be really amazed at the detail this skywatcher 120mm achro is giving me in white light, remember each of these convective cells is only about 1500kms across!

I’ve been away from imaging due to the bad summer collecting data with my magnetometer and currently planning a VLF receiver for capturing solar flares, hence the lack of interaction.

¤········Subject: Happy Anniversary Neptune!

Received: Wed 13 July 2011 06:32:09 JST


 Today, July 12 2011, around 10pm Greenwich Mean Time (pretty much now) planet Neptune has completed one orbit around the Sun (so 360° in terms of heliocentric longitude) since it was visually discovered in the night of September 23 / 24 1846 in Berlin by Johann Galle and Heinrich d'Arrest, confirming the calculations by Urbain Joseph Le Verrier and later also those by John Adams. Neptune is now almost on the same spot as it was when first seen back in 1846.

At the Roseland Observatory in Cornwall, Brian Sheen organized a small event this night, celebrating the completion of this first orbit.

 As far as I am concerned, ever since I started making film (2005), I have been wanting to make a film, in fact a fiction and a documentary film,  about the incredible story that led up to the visual discovery and the events that followed it. I have set several steps along that way, together with a few other people.

 This spring I decided to start filming for the documentary, all still quite preliminary and without support from any TV or production company.

 A number of people have helped me and I thank them very much.

 At the moment, the project is standing more or less still, due to the lack of financial support, but I do intend to continue and perhaps this short extract will help, who knows.

 Here is a first tiny bit of the English part of the story edited together, just to give you a feel. It is nothing finished and some of the editing is a bit on the experimental side. But perhaps there are a few things in there you didn't know yet :

 Take a look on my Planetary Science Channel on VIMEO, where you can find this film, which I called 'Searching for Neptune' :

 I am looking forward to making the full version of the documentary and the fiction film as well.

 In the mean time, you might also want to check out these links here:

 Happy Anniversary Neptune!

  Dear Christophe, Thank you for your prompt reply. PdM's Nov 2007 image is great! I hurried myself into reviewing 2007's pre-opposition HST images and the probe images with similar lighting conditions, as well as ESA ROSETTA OSIRIS image on 24 Feb 2007(attached the other day) for checking confusing albedo features around the Elysium volcanoes. …And now, I also believe the renowned 1-meter Cassegrain's image easily (of course with the imagers' good skills) shows the real relief natures of Elysium Mons and Hecates Tholus with their true sizes.

 The comparison with Damian PEACH's image is very interesting and informativeit may give us a hint as to how an excellent imager's near-the-limit works can show on/below-the-limit Martian features.

 Have a good vacation! Expecting your next draft,

  Dear Reiichi, Masatsugu,

I'm sorry I've belayed the work about Elysium a bit - I will work on it on the following days, but it looks more reasonable for me to publish it on the august issue of ISMO.  From Wednesday I think, I will be on holidays in my usual summer residence in Morbihan, next to the coast, but we don't have internet other there, however from time to time I go back to my parent's home 25 mn away by car to take some "news of the world"...

By the way Masatsugu requested me to see the PdM's image taken in November 2007 - here it is. It has been made by Jean-Luc Dauvergne (journalist at Ciel et Espace) and François Colas. Right now I don't have the exact date. It has been taken in near IR, and I believe it shows Elysium Mons and Hecatus tolus as small relief structures... what do you think? I include also a comparison I have made that year with an R image taken by Damian, that we used to discuss on an Astrosurf topic. One could guess the same structures, but the diffraction makes them bigger than reality.

Best wishes,

Christophe PELLIER (Nantes, France)

Hi Guys

 Here are three images that bring my backlog up to date. Seeing was very iffy through cloud and off cloud edges, with variable brightness of course. I find R6 does not like these conditions.

  Still, a few images were captured, no mosaics as no continuity.

  The "arm like" filprom was very bright and looked like it might do something exciting, but alas no. An interesting feature nevertheless.

Dear Dr. Minami,

Thank you very much for the received "Communications in Mars Observations No. 386".


I really want to be in the mailing list of Mars info because my first dissertation was devoted to disk-integrated and disk-resolved photometry of Mars in great opposition of 1971 and also in 1973 and 1975. I was lucky to observe Mars during three global dust storms on it. The obtained results were published that time only in Russian and they are not known to planetary community. But in October of 2010 I participated in the conference "Schiaparelli and his legacy" in Milano and Torino and reported those results which are published now:

¤·······Subject: Pseudo-relief -like images of Tharsis Montes 

Received: Sun 3 July 2011 16:08:42 JST

   Dear Dr. Minami, Christophe,

Attached here are some HST images taken during near-opposition period in the 2003 apparition to show some examples of pseudo-relief-like images of Martian volcanoes in the extreme vicinity of limb areas which I have mentioned in my latest email.



On the left side is the “Hubble's Sharpest View of Mars” monochromatic image(R? Orange? Green?, I don't know…) taken by HST ACS on 24 Aug, four days before the opposition. The color image in the middle was taken simultaneously.

 On each 24 Aug image three Tharsis Montes can clearly be seen along the western limb in very much shadowed-relief-like appearances (arrows). As they were taken a few days before the opposition, the dawn terminator was

just over the western limb; so that in the area near the morning limb, any shadow effect could have most hardly been expected. Possible causes of the 3-D appearances might be as follows

(1) Difference between the sun's lighting angle with the far side slope of the flank and that with the near side one for each volcano, which might have resulted in a considerable difference in the intensity of sunlight reflection between off the flank over the summit and off the one on this side.

(2) Albedo features around each volcano area which might have caused a mimetic relief looks in the limb area.

(3) Influence of the mist along the morning limb.

(4) Embossment-like pseudo-pseudo-relief-like image caused by excessive image processing.

 For the HST images (4) is unlikely because of their high qualities compared with each volcano's image size, while it seems it should be kept in mind in inspecting ground-based Martian images.

 As for (2), you can check on the 27 Aug image (the right side one taken on just one day before the opposition) the albedo features around Tharsis Montes area. I feel the features could have hardly contributed toward making the relief-like images of the volcanoes in the dawn limb areas.

 Then for (3), on the color HST image in the center, faint mists or clouds seemed to affect the appearance of the volcanoes, whereas on the monochromatic image with the least influence of mists, shadowed relief-like appearances are still conspicuous. So that the effect of the morning mists or clouds seems to be unlikely also.

 Thus my conclusion would be (1) above mentioned is most likely.

 Besides indicating Arsia Mons, the green arrows are intended to point the delicate notches on the limbs just over the volcano. In the 2003 CMO Mars Gallery, on some images taken in the period around the opposition day, extremely conspicuous dark spots are recorded on the morning limbs just over Arsia Monssome examples are on the images of

Donald C PARKER:  25 Aug 2003 04:17 GMT ω=058°W

George HALL:  29 Aug 06:30 GMT ω=056°W

Ed GRAFTON:  29 Aug 06:47 GMT ω=059°W

Were the dark spots other Fœhn Phenomena!? …Were the notches on the dawn limbs on the 24 Aug HST images related to the dark spots captured on the CMO colleagues' images?  Best Wishes,

     Reiichi KONNAÏ (Fukushima, Japan)

Attached:  HST 17 May 1997_CM175 ENH.jpg, Profiles of the Volcanoes of Mars.jpg, 2007 PCq's Elysium Images with decreasing longitudes.jpg, ESA ROSETTA OSIRIS 24Feb2007.jpg, G. Fournier's Drawings of Elysium in T.Saheki's Book.jpg

    Dear Christophe, Sorry to be late in replying, I spent two days in Tokyo Disneyland with my dental clinic staff, scared by a lot of roller coasters and free fall machines!  I have read through your draft on Elysium Mons, as well as Dr. Minami's email to you he had Cced to me.

 I agree with your conclusions that (1) the ground-based detection of dark Elysium Mons with our instruments may be possible but extremely challenging, and (2) the detection of the brightness of the volcano near opposition period is much easier which implies the exposure of the bare Elysium Mons.

 Last year I made a review of shadowy images of Martian volcanoes taken by HST and the probesI found on some shots that Elysium Mons was recorded as a snug little dome-like relief image of about 150km across(attached is an example of morning side relief image). Around 150km in diameter is much smaller than the catalogued size of 200~300km, probably because of its conical profile.

 For the detection of a dome-like geographic structure's shadowed relief image, the formula to get the minimum telescope aperture required to recognize km across crater which I introduced in my recent LtE may be applicable; same logic though the sunlit and shadowy sides would be opposite.

 Then the minimum telescope aperture to discern a 3-D mound image of 150km across on the 20" Martian image would be 52cm so it seems no easy even for the skilled ISMO colleague imagers to obtain explicit relief image of the object.

 Actually, most of the candidate images show relief-like images of Elysium Mons swollen up to almost 250km across. I myself want to consider that our excellent imagers managed to succeed to get the true shading of the relief of Elysium Mons, though blurred by the optical limitations and the seeing conditions. But they are all questionable as the hourly changes of the dark portion on the images around each candidate shot are quite uncertain.

 As for its summit caldera, it's only 14km across and might have nothing to do with shadowy appearance in any condition.

  As to the bright Elysium Mons, it must be by far easier optically, and with the favorable apparent Martian size near opposition, so we can find many many examples in the CMO Mars Galleries.

 I agree with Dr. Minami in the point that in the period near opposition any relief topography would be most unlikely to show any shadow with usual meaning, so that the shadow-like parts are due to albedo features. However, I have noticed on some HST images of near opposition that some Tharsis Volcanoes showed very much relief-like images in the extreme vicinity of the limb(not terminator) areasmight have been, I guess, pseudo-relief-like images caused by the greater difference between the sunlit angle for the far side slope of the flank and that of the near side one for each volcano, which might have resulted in a considerable difference in the intensity of antisolar brightening between the flank over the summit and the one on this side. A similar effect may be seen on Elysium Mons when located at the near opposition limb.

 Otherwise, I have nothing to request you for now to add, cut, or reconsider the contents of your draft.

 Dr. Minami seems to expect us to make the note a little longer with some speculations upon the peculiarity of the volcano itself. But this time I think it's OK as your plot as “A Brief Review of Bare Elysium Mons as detected by the CMO Colleague Imagers". Bright Elysium varying apparition to apparition, probably influenced by the meteorological / geological conditions, is very interesting, deserves to be discussed in the future leadoff article, or note in CMO/ISMO.

 I am also attaching some more images and scanned figures for your reference

  * For the profile of the volcanoes of Mars, the vertical scale is exaggerated four times.

  * PCq's 29&30 Dec 2007 images may show some changes for different positions of bright Elysium Mons on Martian disks but can be questionable.

  * ESA Rosetta Osiris 24 Feb 2007 passing by image is fantastic! It's a missing link between HST images and the probe images which gives us an idea as to how the craters near the Martian terminator look like with a powerful telescope. Interesting albedo features around Elysium Mons are notable.

  * G. Fournier's drawings in Tsuneo Saheki'sMars and Its Observation", p.242 may show dark Elysium Mons with its true size.…Do you know other examples of “Pre-PdM detection of Elysium Mons by visual observers or by Martian photographers?  Best Wishes,

  Reiichi KONNAÏ (Fukushima, Japan)

It took some time to process these Saturn from one month ago, taken under a very good seeing (these Saturn are probably ones of my best).

A very large collection of most images from UV to CH4 absorption band, with a map of the GWS with many details (small spots, double head, dark zones, ...). To be noted the head gets really brighter on the last RGB when close to the meridian from the RGB before, i do not know if it's only an optical effect.

A montage (Saturn in RGB, satellites in IR) with Mimas below the left ring, Enceladus on below the right ring, then farther Dione (bottom), Tethys and Rhea (at the right):

Same in full R+IR:

Dear Masatsugu,

   The talk that I gave--and you have seen only the first half--was mainly to inform the audience that Percival Lowell had an adventurous career before he decided to devote himself full-time to astronomy.  Surprisingly, few of the audience knew of his career as an expander of Western Consciousness about what was then regarded as the Inscrutable East.  I shall send the references to the rest in due course.  The talk was very well received by the audience.  I was told to make it "friendly" and to aim at a very popular level, as none of these individuals could be assumed to be familiar with much of the material.  There were some astronomers there however who told me they enjoyed it--including Otto Franz and Wes Lockwood.  It seems to have successfully completed its assigned task.

   It looks as if I will return to Flagstaff in the autumn to do work in the archives--there is a great deal of interesting material about Lowell that has hardly been scratched; including his copy of Newton's Principia (a nineteenth century version) and his love letters to Miss Struthers, who refused his proposal of marriage because he was not religious and she did not want to hurt her parents who were.  Lowell continued to describe her as his "mundane Venus" in correspondence with her even after his marriage to the rebarbative Constance--I have seen letters to her written as late as 1915.  (I am sure he did not show them to his wife.)    Jean Cavé, whom you met in Paris and who has now finished his novel on Percival, was especially taken with these letters, as you may imagine!

   I read just this morning your essay on Mellish in the latest CMO.  You masterfully demonstrate how little many of those who argue for the "flat Mars" know of the mathematics that predicts shadow lengths near the terminator.  Jeff Beish's analysis is shown to be superficial and deceptive (as you say, he uses a flat map to show Mars is flat!  One could do the same with the Earth).  I am glad I sent the Mellish article to you as it has obviously pleased so many of our fellow "aeroholics" as Reiichi Konnaï so justly describes us.

   I have quite a large number of projects pressuring me now but hope to turn out something soon on Lafcadio Hearn's experiences in New Orleans; that cosmopolitan and very colorful place served as something of his apprenticeship for Japan, just as Lowell's time in Japan (especially Noto) served as his apprenticeship for Mars.

   Best wishes,

   Bill SHEEHAN (Willmar, MN)

¤········Subject: The Variations of Belts on Jupiter in 2009-2011  

Received: Wed 22 June 2011 14:38:51 JST

Here is shown the change of the widths of the Jovian SEB and NEB in 2009, 2010 and 2011. They turned out very changeful during the three years. They are not on the correct latitude lines here because the geocentric latitudes of Jupiter change every year. However we roughly prove that SEBn and NEBs are not so on the changed lines, but those of SEBs and NEBn have changed: Note that the NEBn did in particular. The latitude changes periodically and we can observe the dark barge and bright spot on the latitude.

As is well known, the SEB belt was not observed in 2010. SEB disturbance happened in November, while its belt revived after a while. The width of the SEB increased this year. Note the change of density as well as the position change of the GRS.

¤········Subject: Re: Your post address

Received: Tue 21 June 2011 22:24:50 JST

  Dear Masatsugu, We do have a new address. I read and enjoy the CMO, and I would appreciate it if you could continue to send it. Please forgive me for not notifying you sooner.

I will mention briefly, since I type slowly now with my left hand, that I think it unfortunate that Jeff Beish was called an idiot in CMO #385. Whatever else he is, Beish is no idiot. He is -or perhaps now was- a friend of the CMO and of ALPO. There are not so many of us planet observers that we need to pick fights. Instead, we need to help and encourage one another. I would humbly suggest that an apology from the LtE writer would be appropriate. My "gut feeling" is that an apology might sooth some hurt feelings that could otherwise cause even more problems later. I have not communicated recently, in the last few years, with Jeff, so this is my suggestion, not his. Years ago Jeff came across as sometimes abrasive but approachable and good hearted. Bill Sheehan is certainly a big enough man and author to survive admitting one mistake. I like Sheehan's books very much.


Three collections of my poems are now available at Perhaps you will like the following, from Meeting and Passing:


My Own Left Hand

For most of my life

my left hand's role

was purely ancillary.

It guarded distant borders,

nibbled at the soft underbelly,

and tried hard to avoid

the major clash of arms.

My left hand rode to work

or ran to play

at best as a sidekick

or an almost useless appendage.

It did its job,

if there ever was one,

without fanfare, thanks, or even notice,

in neither sense of the word,


Now Parkinson's lies

on my right side

like a heavy load.

Grasping for handholds,

not straws,

I grab the old

and unappreciated friend

my own left hand.

A little less than everything

but much more than nothing,

it holds me

for the moment


under Heaven

and over the abyss.


under Heaven

and over the abyss,

your friend Sam

¤········Subject: Note on Elysium

Received: Mon 20 June 2011 02:54:59 JST

Dear Reiichi,

Here is a first quick draft of an ISMO note about Elysium. Feel free to comment, add, disagree, in my mind it's truly a working document.

Masatsugu, feel free also.

I think I have found some images where we can see Elysium (as well as Hecatus Tholus) as a relief detail and not only albedo. Shadow effects however are a bit difficult to see; bright reflection near opposition is probably the most conspicuous effect.

Best wishes,

Christophe PELLIER (Nantes, France)

PS: Masatsugu, what is the CMO code for Reiichi ?


¤········Subject: Transit of Venus Project newsletter #1

Received: Sun 19 June 2011 01:09:15 JST

  Dear colleagues,

It has been two weeks since the Transit of Venus Project's website

was launched, and even in this short period of time it has been much improved. The transit calculator is now online, allowing you to compute the contact times for any given location on earth. Also, Rob van Gent agreed to host his extensive transit of Venus bibliography on our website. There's still a lot of work to do before all of his bibliographic entries are transferred (the Bibliotèque nationale de France decided to change their permalinks on the Gallica website), so please return in the next couple of weeks to see for new additions. Together with the list of locations of historical observations, the project's website now forms the most comprehensive resource for anyone interested in the history of the transit of Venus. In the section "Getting involved" you'll find the activities currently adopted by the Transit of Venus Project. More will follow, but for now I would like to introduce to you the three activities already open for all to participate:

Experimental archaeology

What did astronomers in the past actually see? What did the black drop look like through an eighteenth century eyepiece, and could the aureole effect have been observed at all, as is often claimed? By observing the 2012 transit of Venus with antique telescopes, this project hopes to find an answer to these questions. Contact: Randall Rosenfeld (

Mark that site!

Many of the locations where astronomers observed the transit of Venus in the past go unnoticed today. Still, these places tell exciting stories. This project's objective is to relocate, inventory, restore and eventually mark significant sites of past transit expeditions. Contact: Steven van Roode (

Measure the Sun's distance

This experiment - proposed originally by Edmond Halley, forming the driving force behind the historical expeditions and re-enacted on a large scale in 2004 - will be repeated again in 2012. This time, however, we will make use of modern technology, much of which wasn't even available to us in 2004. Measuring of the contact times and submitting your data will be facilitated by an easy to use (and free) phone app. Contact: Steven van Roode (

Finally, I would like to draw your attention to our fund-raising campaign. We need funds to start developing the phone app for you. See

for more details of the phone app. Please support the Transit of Venus Project by donating $50, $100 or more! You can use the donate button on our home page to contribute your gift. Donations are made to Astronomers Without Borders and may be tax deductible. Just think of how wonderful it would be if you could find and send your contact times with a free phone app on June 5 or 6 next year, without the need to leave the eyepiece. And hundreds of thousands of others will benefit from your donation too!

In the mean time, if you haven't done it already, please consider joining our group on Facebook:

 I never had so many telescopes for myself as now, but I have no time to observe. Also seeing is constantly poor here from my country house near Rome, this is why I hope to place a remote controlled telescope in a better place and hopefully get back to do some planetary imaging.
