Hi Guys, It seems you either get prominences or surface detail, but not both at once. There was a large patch of low activity in DS but cloud stopped play. Two nice proms were on display and a new AR was appearing over the solar horizon. This was fizzling with activity some of which is captured here.

¤·······Subject: Transit of Venus Project Newsletter #3

Received: Tue 16 Aug 2011 18:31:48 JST

Dear all, The 2012 transit of Venus is now less than 300 days away. Venus just reached superior conjunction and is now definitively on its way to transit the face of the sun next June. Last month we introduced a couple of new projects and activities:


Creating 3D models of transit sites

Even if you’re not in the position to physically mark a historical observing site, you can still substantially contribute to the Mark that site! project. Marking sites can also be done virtually in Google Earth. There’s already a Google Earth file with all the stations listed on our ‘Past transits’ page. What’s still missing are 3D renderings of the observatories. By building 3D models of the observatories in Google Earth, people will have the opportunity to get an idea of the layout of the domes and cabins astronomers lived in for weeks, sometimes months, under difficult circumstances. These models can also offer a means to project the written accounts unto the factual surroundings, explore sightlines and examine the orientation of the buildings with respect to the heavens. If you have plans to model one or more observatories, please contact Steven van Roode:


Recovery of old transit photographs

July 29, Randall Rosenfeld made a bold appeal to institutions and archives to see whether they have transit or transit-related photographs with intriguing stories lying in obscurity awaiting recovery. Are there any in a collection near you? It might be worth your while to find out, particularly if an institution in your area sponsored an observing team in 1874 or 1882. Please contact Randall if you found any interesting items:


Transit of Venus merchandise

Two weeks ago we opened a webshop where you can buy mugs and shirts. It's a nice way to let people know of the upcoming transit of Venus. Imagine how wearing a transit of Venus shirt could serve as a conversation starter. If you are planning a public observing session on transit day, you can make your team stand out as members of the organising crew. There are now two basic designs: one with the Transit of Venus Project's logo, and one based on the golden medallion commemorating the 19th century French expeditions. More designs will be added to the shop soon.


Phone app

I would like to thank all of you who already have made a donation to fund the development of our phone app. But we're still $13,000 short to pay for the development costs. Be bold and make or increase 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. The main purpose of the phone app is to help you with measuring the times of contact, and to enable you to submit your timings to our website ? all with just two taps on your phone's touch screen. Once submitted, your timings will be used for a real-time measurement of the sun's distance. For more information, see the detailed plan on Chuck Bueter's website:

 Your donations will be made to Astronomers Without Borders, and these contributions may be tax-deductible.


You are also invited to join our group on Facebook:

 If this newsletter was forwarded to you and you would like to be on our mailing list, just send a message to and you'll be kept in the loop. If you're thinking about contributing to our website, don't hesitate to contact us!

Clear skies!

Under good seeing, and that time my telescope was optically aligned:

Some details can be seen inside the GRS, and following it in the SEB there are some eruptive bright spots (one can be made out in the methane image) which are recent (not present a few days before). In methane image, again only the preceding south part of the SEB is dark.

The aspect of the STB is extremely interesting, it looks like the preceding section preceding would be linked to the GRS, and the following section is spread out in latitude in the zone. The longest of the two barges in the NEB as a clear spot inside, and two small spots are visible in the north polar area in the methane image.

 Also here are animations of all RGB and IR images:

And here are 2 montages (first a mix of RGB and IR, second full IR) of Jupiter, Io, Ganymede and Europa:

¤·······Subject: Dark segments following Arsia Mons

Received: Sat 13 Aug 2011 12:48:01 JST

 Dear Dr. Minami,

While I was wandering through the Web last night, I have stumbled across a drawing of Mars by Prof. Shotaro MIYAMOTO on 1 Sept 1971 which may show a dark segment near the dawn terminator, west of Arsia Mons. LCM was almost the same as those of the images by Isao MIYAZAKI and Jose SURO which I have mentioned in my latest LtE, and the season might have

been around that with λ=245°Ls. Was that a same phenomenon as recorded in 1988 and 2003?(though possibly the shadowy Arsia Mons itself because the drawing was taken some twenty days after the opposition day).

 If that was the case, then we can say we already know the probably meteorological phenomena occurred in these three consecutive major Martian oppositions. I am also reviewing the drawings by Japanese observers in 1956 apparition.

  Good Seeing with Excellent Scopes!

¤·······Subject: Dark Segment west of Arsia Mons

Received: Thu 11 Aug 2011 19:43:15 JST

Dear Dr. Minami,

In response to your question in your email on 31 July, I reviewed Isao MIYAZAKI (My)'s TP shot on 30 Sept 1988 at 14:39 GMT (ω=065°, λ=282°Ls, φ=22°S, δ=23.5", ι=04°,with 40cm Newtonian). The dark segment following Arsia Mons at the dawn terminator was right there. In the 2003 Mars Gallery, I found an image taken on a near-opposition day with almost the same CM as My's 1988 photo; the image by Jose SURO on 27 Aug 2003 at 05:45 GMT (ω=063°W, λ=249°Ls, φ=19°S, δ=25.1", ι=05°, with a 28cm SCT) looks to show exactly the same phenomenon as recorded on My's shot.

Taking their locations and extents into account, they were not, I think, the huge volcano's shadowy reliefs at opposition à la Christophe PELLIER. They might have been caused by some other meteorological process, like the one you have proposed in CMO 2005 Mars Note (13) in CMO #330…possible morning side Föhn phenomenon over Arsia Mons. Is the phenomenon not so rare in Martian southern summer?

 Good Seeing with Excellent Scopes!

Received: Thursday, August 11, 2011 2:41 PM

Hi good morning Masami san, here are some observations of Uranus and Mars performed last 10th.


with the time being features become very faint in contrast for not saying confidential.

The main topics: dark south hemisphere and clear south cap.

EZ is suspected but probably not here on the view.

Would be interesting to watch at different CM values to see if EZ is present partially for the least (at sun set side seems to be, only). Not the patch and features collected last opposition. The disk remain bright in blue color with no perceptible darkening edge.


Solis Lacus area accessible. At the terminator edge bright area (revealed and shown as C, clear) in yellow color. The north pole area whitish (hood?). Argyre very clear collected. Chryse clear also (brightness area were quoted in comparison). Almost fixed images on Mars (height 28° only) and on Uranus (height 41°) on this morning with 360x and the RC200. For your perusal. Good skies. Faithfully

Dear Masatsugu,

   Still mulling over the Lafcadio Hearn essay--but meanwhile I will respond to the question about the Basho quote (or rather misquote).

   The full passage reads:

   "Sun overhead before we left the shrine, we hired a boat to cross to Matsushima, a mile or more away.  We disembarked on Ojima Beach..."

   This then is the place where he finds inspiration of the feminine beauty in a shining world; and refers to the mountain god Oyamazumi (I misquoted!) as having made it.

Dear Masatsugu,

   In the Galaxies book (my Guggenheim 2001 project which has now been an off and on thing for ten years), I write the following passage, which I hope you will peruse for accuracy.

   I will try later today or tomorrow to jot a page or two about Lafcadio Hearn.

   Best wishes,


Even from the northern hemisphere, the Milky Way, seen from a clear dark site, exhilarates with its magnificence.  One northern hemisphere witness to its grandeur, the Japanese haiku writer and pilgrim Basho, (1644-94) looked across the sea to Sado Island, where political exiles were confined, and exclaimed:


            High over wild seas,

            Surrounding Sado Island --

            The River of Heaven!   [i] <#_edn1>


   Basho wrote that haiku on the eve of Tanabata Matsuri (the “Evening of the Seventh”), a Japanese summer star-festival celebrating the reunion (for one night) of Orihime and Hikoboshi, represented by the stars Vega and Altair. According to a legend originally imported into Japan from China, these personalities were separated from one another by the river Amanogawa (literally, the “heavenly river,” i.e., the Milky Way) but are permitted to meet again for one night a year (on the seventh day of the seventh lunar month of the lunisolar calendar). [ii] <#_edn2>

   For the Northern Hemisphere lover of galactic wonders, the separation is not by but from the Milky Way or at any rate, from some of its most brilliant aspects. As the Galactic Center, in Sagittarius, lies at 20 degrees south latitude, only from places south of the equator can the lover embrace many of the most gleaming objects of his (or her) desire.

   Travel to Chile, to South Africa, to Australia, to New Zealand. Let it be during the northern summer, which also happens to be the southern winter; not the time that most pale-faced sun-worshippers disembark for southern latitudes. It is a long way to go for those cabined and cribbed in northern cities but well worth the journey. It is a worthy pilgrimage for the star-lover. Again Basho's words are brought to mind:

  Here one is almost overcome by the sense of intense feminine beauty in a shining world. It must have been the mountain god Oya Mozumi who made this place. And whose words or brush could adequately describe a world so divinely inspired?  [iii] <#_edn3>

Dear Christophe,

Yes you have been looking for poked out EM images! For a complete set of RGB/LRGB and the components especially with good B or UV image showing shadowy EM, examples may be extremely rare, almost none. …

However, I think I once have seen such a set of images, in the CMO galleries? HST images? or in the probe images like ESA Mars Express' raw images, I just forgot. May be my memory is confusing with an image with the developing dust storm. I'm gonna make a review for it later.

 By the way, I have to make the Japanese translation of the note for the coming issue of CMO Japanese version. Dr. Minami will probably send me a laid out PDF.

But could you inform me if you make some change in the manuscript?I'm not good at the Japanese language, so the translation takes time!

Dear Reiichi,

I had seen the two HST images that you refer to but did not retain them. For the 3rd may 1997, the summits look just outside the mist for me; and for the Feb. 95 image, I think that we just see Elysium through the mist, note above the mist. I mean that it's faint and that we just see the ground by transparence...

The Elysium region produces much less mist than Tharsis, if do not say silly things, and is located further to the north, so it's generally free from the influence of the equatorial cloud belt observed during perihelical apparitions. We may just lack situations where we would be able to decide if it's able to poke or not.

Now about Don's image, I just sincerely do not see the two Mons on it...

And on the 3 Apr 2010 image by DPk which Dr. Minami pointed out in his latest email to us, I think relief (like) EM image can be seen through the morning mist (please check attached enhanced image).

 The reason we can't find the image of dark EM poking out of the morning mist may be…the mist appearing over Elysium area may be thick or high, EM is not so high(already on the Elysium Rise of relatively small extent), or the flank and the caldera of EM may be not so dark as Tharsis cousins, etc.…

  Dear Reiichi, dear Masatsugu,

Please find attached the developed draft for the Elysium note. The figures are in the zipped file as well as in the text.

The conclusions were a bit changed since the first summary draft, as I propose some relevant images for a possible detection of a relief effect on amateur images. I have not included every aspect we have been sharing since two months by e-mail; please add anything you find interesting. Especially, a word about the "non-poking" aspect beneath morning mist must be included I think... I did not found any example either on HST data (and I have a lot).

About the aspect during the 2001 dust storm; I have attached a pdf complete article from Wang, Toigo and Strausberg where you will find good MGS images. On figure 9 (page 19) we can see EM and HT darkened by the storm, I think; the dark Tharsis volcanoes show up very well on the same images.

Best wishes,

Jupiter under average conditions with a smaller focal length than usual (a bit too small to my opinion):

As on other amateur images, we can see the white rifts following GRS and passing north of it, the aspect of the SEB in methane (only SEBs preceding GRS is really dark), the dark barge in NEB, and a white spot rising between south of NEB and EZ, which appears white in methane absorption band.

Here are a couple of shots from July 30th. The sky didn't really clear properly until the afternoon and the seeing was a bit wobbly as a result. The three active regions chasing one another across the disk are the key features with a smaller 'hotspot' appearing to the west of the trio.

 Dear Reiichi,

Yes it was quite fun because I could "simulate" every view I wanted! It was painted in 2002; at the time I had not witnessed any perihelic apparitions but the intermediate 2001 one (a bit too young to really observe in 1986-88-90) and I had almost only observe the northern hemisphere of Mars. I was eager to anticipate the change of geometry; The markings are those prior to the 2001 global storm (I had mainly painted it from MGS data and HST photos).

Yes Hellas and Alba Mons are at the opposite... I heard once the idea that the Tharsis bulge burst because something had penetrated deeply into the planet from the opposite side, leaving an enormous scar - Hellas. Don't know if this is possible...

 Here are a bunch of images from the 28th seeing was not good, but good view of the new spots was had.


  I have been experimenting with my single stack setups and white light. The white light images were taken with a IR 742nm, pass filter as opposed to the normal Green Baader solar continuum filter. On this day the IR did a better job in the seeing. 

 Note the subtle difference in spot detail on the montaged  comparison  image between ,5 and .7A  the field lines go right into the umbra on the .5A. The smaller spotlets are more visible in .7A

 Dear Christophe,

What a fantastic real Mars globe, and how sad to hear the paint was finally ruined! I guess you already have many virtual Mars globes of various apparitions in your PC, but I believe the old real globe of your own painting which you could have been holding in your hands gave you a lot of special fun.

 I myself have several ready-made Mars globes. Next door to us is a cozy pub (our home/clinic is in the midst of our town's combat zone, once the red-light district) where I keep my own personal bottle of sake as well as my smallest 12cm across Mars globe. It's great fun drinking at the corner seat (almost for my exclusive use) with my globe…I noticed on it the other day that Hellas Planitia and Alba Mons form perfect antipodes! I hope I can enjoy my sake sometime with a Mars globe of my own painting!

¤·······Subject: observations of Mars and Uranus this morning 30th

Sent: Sun, 31 July 2011 00:01 JST

Good afternoon,

Enclosed here some observations of Mars and Uranus performed with the RC200mm F9 Vixen. Not bad seeing during the period except at the sun rise levels becoming worst.

On Mars:

Hellas at the limb is bright. Eridania as well. The terminator side seems hazy. Mare Boreum and Utopia well accessible visually without being contrasted as features in south part. Difficult to say more.

On Uranus:

The south cap is clear. The south hemisphere is darker than the north (seems to be constituted with 2 band system (W8 filter). The dark border of the south cap with the aid of the light blue filter is still here but fainter. With no filter, the equatorial zone seems to be, but suspected only. Difficult to say more. Indeed the given contrast levels are amplified for the report.

Observation conditions are given on the sketches.

For your perusal. Best regards

Received: Tue 26 July 2011 21:42:56 JST

Hi Dave,

I do agree that the HST image you're referring to has an excellent color balance. HST views can be a good reference, though they are not always perfect. Some are made with color layers that do not belong to the visual range or do not exactly match it (I think that the 2009 one was assembled with an UV layer instead of blue, for example). However this image is made with a synthetic G image ; that way a given image can look perfect yet a true G filter would have brought different nuances. On many of the RsGB image I have tried on the past on Jupiter or Mars, the results looked to take on an orange hue that was not really natural...

They are many things that will make the colors change on an image and this makes the research of a sole reference a bit hazardous. Even seeing conditions will tweak the balance because they will artificially change the relative contrasts on each R, G, B frame. Different cameras, different filters or processing methods (in this respect, I find that many LRGB images we are sharing are not correctly colored : the grey L image is still showing on the final image and the colors are too pale)...

Although I'm personally very careful about colors, because of all this I have no hope of getting "the" true colors. I prefer instead the concept of "reliable" colors : you will have different nuances for different observers, but once they are skilful and pay attention to this problem, you'll still be able to rely on every images to interpret what' going on the planet.

For example, last year's GRS was colorful; but deep orange? Reddish orange? Pinkish orange? All this nuances are not that important providing you still can tell from them that the color was intensified (but if it was grey pink on an image, then it must have been declared "unreliable"...).

At any time, having knowledge about a planet is a great help. If you know how a given detail must look on the image, this will help you to find the color (... or to decide it definitely does not have its usual tint!)

Finally a direct view at the eyepiece is not to be forgotten. Look at the planet and try to define the colors. Your eye has its own limitations, however from CCD it has the advantage of not being able to make informatical processings;

Best wishes,

Christophe PELLIER (Nantes, France)

Hi Guys, John has just put up some Jupiter images from Hubble as part of the SEB discussion.  There has been a lot of comms on ALPO about Jupiter colour and screen standards etc. It does not really matter what guys set their screen colours at, we will still get just as much variation.


 In my opinion the only way they will ever be anywhere near the same, will be if everyone has the same colour reference image on screen whilst processing. 


To this end, I personally think the Hubble shots are a good reference. The composite John has put together from Amy Simon's data is how I personally like to See Jupiter and is how I see it most often portrayed on the TV programs.


I do hasten to add I agree it is often about personal taste and that this is only my personal preference.  I have made the oddly coloured Hubble image in the set, to appear the same as the Amy Simon shot.


Our brains have a built in auto white balance and if we look at almost any coloured image long enough it will appear correctly colour balanced. Now if you put alongside an image you previously accepted as correct it will show how grossly poor we are at judging colour from memory. 


Some Musicians have perfect pitch but I don't know anyone who has the "chromic" equivalent. 


Chris's color images are the most consistent I have ever seen.   He does have the planets pretty well over head forever which is a great help.  

 Have fun Guys

Dear Sirs,

Here is my first contribution about Mars present opposition performed with the 150mm refractor.


I attach also here a first view of Uranus with the same means.

I would like to raise a question to the Mars section:

"During the Meudon meeting it was set a proposition consisting in affirming that the blue clearing effect remains more coming from the reflectivity properties of the ground more than the scattering properties of the high layers of the planet atmosphere".

This is an interesting study but when considering this proposition which kind of investigation methods can be undertaken in order to split such, or hopping to discriminate such? Is it possible to expose such investigation methods in the CMO bulletin? This could be interesting for the community of observers.

Received: Mon 25 July 2011 00:14:20 JST

  Dear Christophe,

You are absolutely right in interpreting the relief-like images of Tharsis Montes and Elysium Volcanoes…they are indeed real relief images:

  I carried out a simple primitive simulation to test how huge Martian low-profile volcanic mounds look near the limb in near opposition period:

  An equal-proportion “Olympus Mons" was made with white clay on a styrofoam sphere of 15cm across. Then the sphere was lit with a collimated light beam with “the volcano” located near the terminator. And it was photographed at two different angles to make a half-Mars shot and a full-Mars one respectively (attaching here). The result needs no explanation, it shows a real relief image of a shadowy side with a sunlit side of the mound just as you pointed out. The low-profile seems to be the pointA steeper peak enough to cast long shadow will result in “shadow hiding” by the peak itself to render it non-3D appearance in the vicinity of near opposition limb.


  Also attached here are very interesting images captured from the ESA Mars Express's animation:

You can see many many familiar features in this animation; Tharsis Montes, Argyre, Douglass & Lowell craters, NPC close-up, shadowed Apolinaris Patera, Valhalla on the terminator, AND the shadowed Elysium Volcanoes coming out from the dawn terminator! Dashing Phobos and its shadow also

 Dear Reiichi,

I'm making an answer to you quite a long time after this message, but I'm actually fully working on the note so I'm re-investigating all our correspondence. I think on my part that the 3D effect is real, is really an image of a shadowy side with a sunlit side of the volcanoes. The final proof of that is that we can detect from the Earth, on amateur images, the progressive darkening of the shadowy parts with the our (we can also see this on "Valhalla"). It can of course, be artificially enhanced by strong processing, but is not really what I would call an artefact.


 >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

06:30GMT ω=056°W Ed GRAFTON 29 Aug 06:47GMT ω=059°W …Were the dark

spots other Föhn Phenomena!?


Oh that's really interesting. This very dark line was absolutely intriguing at the time... but we will note that it's darker in red light. It should be less contrasted in red light? Hall and Grafton are respectively RRGB and R/IR-RGB processing, the ones that eliminate strongly the atmosphere on (pseudo) color images. Yet it still shows up contrasty.


Back to the note, I have re-processed the Pic image and I have done well (see attached). Thanks to it, it's much easier to detect Elysium and Hecatus on amateur images. In 2007, I have three successful amateurs (Peach, Casquinha, Flanagan). Some in 2003 as well...

Hi Guys

 I have just been experimenting with a DLSR for single frame (as opposed to mosaics, which Lunar eclipses don't allow) whole moon shots, not as easy as one might think to get sharp images.

 This colour shot is only four images stacked in R6. The seeing was not an issue until I saw the rippling in registax. The moon was at 29 deg alt.

 The 5 inch APO seemed to max out the seeing and technique, as a 4 quarter  frame mosaic experimental comparison shot with my C14 was no better.

 The camera was a Canon EOS20DA  with 8.2 Megapixels. The 5 inch AP was 40 inch fl. The 1411 pix high image had 895 pixels spare. The 2336 pix height Chip would just cope with 60 inch FL (Increased the pixel count in the image so as to be 900 high at 50% to fit the screen).  Best wishes

¤·······Subject: SEB aspect in CH4 after a SEB revival

Received: Fri 22 July 2011 07:37:47 JST

Hi all,

We have all noticed the curious aspect of the SEB in the methane (CH4) band this year, especially in the longitudes following the GRS - the belt is not dark, as some of you commented. Suspecting some relationship with the SEB revival of last year I went to check old images to see if there were some preceding occurrences of the phenomenon.

It seems that is has happened already at least twice after an SEB revival; and it comes along with two other aspects in other filter bands:

- In near IR (or R) the SEB is blank where it is "not dark" in CH4

- In B/UV it is "normally" dark.

This set of images present some old HST images taken after the revivals of 1990 and 1993 (sorry the file is big)


In 1991 the CH4 SEB is less dark than it was in 1993 while faded (Pic du Midi data not included). The belt is blank f. the GRS in IR and very dark in UV.

In 1994 this is the same, with a new feature that we see also in 2011: the southern half of the Equatorial zone is abnormally dark ("normal" state is very bright). In 2011 both are almost impossible to differentiate. Nothing irregular seems to show up in all other bands...


After an SEB revival, it has been noticed sometimes an "orange flush" over the SEB (John Roger's work). Well visible in 1991, and to my eyes in 1994 the SEB was pinkish-orange as well. If the belt is dark in UV and clear in IR, then it must take on a pink-orange hue in RGB.

Therefore the "not dark" state of the SEB could be related to the pink-orange color that would then be a mid-level haze spreading over the relevant longitudes?

Final remarks:

- 2008 is a counter-example (possibly coherent): the SEB has a normal dark aspect in CH4 after the revival of 2007, and is active in near-IR. No coloration is noted (BAA report)

- I hardly see the coloration in 2011, except maybe in some small sectors of the belt. Don's RGB included on the set is one of those images; it also shows small reddish points (barges I assume) in the belt also visible in 1991 and 1994.

- Visual observers should make some estimations of the color of the belt, especially following the GRS, this would be most welcomed...

What do you think?

¤·······Subject: Transit of Venus Project searches for an author

Received: Tue 19 July 2011 17:19:04 JST

Dear Masatsugu Minami,

You already might have looked into the international Transit of Venus Project's website, launched about two months ago to get people involved in the observation of the next transit of Venus in June 2012:

The website offers background information, and projects and activities you can join in to. On the home page, blog posts concerning the transit are being published regularly by a varied team of authors: Chuck Bueter (eduactor), Randall Rosenfeld (archivist of RASC), Andrea Wulf (writer), Michael Zeiler (cartographer), Nandivada Rathnasree (director of New Delhi Planetarium), Paolo Tanga (planetary scientist) and myself (high school physics teacher).


Yet, I feel that a voice from Japan is still missing, whereas the Japan has a lot to offer if it comes to the 2012 transit of Venus: an interesting history (1874, 1882), and ”most importantly” the entire transit will be visible from this part of the globe in 2012. I expect a great many observers will travel to Japan in 2012 just to watch the transit of Venus!


I wondered if you would like to consider writing short blog posts for our website on a voluntary basis with a frequency of, say, twice a month. Subjects may range from historical stories of the transit, accounts of the 2004 transit, ideas for educational activities to tips for organising public observing sessions as long as it has to do with the transit of Venus. You may go through the current blog posts to see what has been published so far.


I would be very happy to add you to our team of authors! I look forward to hearing from you.
