Dears,
Under good seeing for the R+IR, but unfortunately with a bad
transparency degrading quickly and ruining my color layers:

Dear friends,

Here's two images of tiny Mars from May 28 and 29, taken under rather poor conditions. Except for the Olympia cap outlier there's not much detail on this contrast hemisphere at this resolution.

I see several days of unsteady weather ahead so this is perhaps my last contribution this apparition. Low altitude and poor seeing will win eventually.

Hi Guys 

Here is an LRGB data set from the 28th,which shows a couple of faint spots. In the WRG Luminance channel, the position of the most northern spot is most dominated by the green channel therefore the LRGB colour image takes the green channel timing.

Received; 25 May 2012 at 19:24 JST

 

Dear all,

In case you have not received new this notice The EPSC Meeting:  http://www.epsc2012.eu/  has extended its deadline for submitting abstracts till next Tuesday 29th May.

We are requesting new abstracts for the AM2 session: Amateur contribution to the advancement of planetary science

 

Amateur astronomy has evolved dramatically over the last years. A motivated amateur, with his/her backyard instrument and adequate imaging processing software is nowadays capable of producing high resolution planetary images in different wavelengths which are better than what professional observatories could produce 15 years ago. Hundredths of regular observers are sharing their work, providing a very good coverage of the main visible planets (Jupiter, Saturn, Mars and Venus) which is very valuable at a time when it is more and more difficult for professionals to access to professional resources focused on other areas of research. Additionally, these networks of amateur observers can react immediately when triggered by a new event occurring on a solar system object requiring observations.

Moreover, some of the advanced amateur astronomers analyze this data to derive analysis which proves to match research criteria and needs, in several areas like planetary meteorology of Jupiter and Saturn, meteoroid or bolide impacts in Jupiter and Venus studies leading regularly to strong collaborations with professionals with an increasing number of published results in scientific peer journals. This session will showcase results from amateur astronomers, working either by themselves or in collaboration with members of the professional community. In addition, members from both communities will be invited to share their experiences of pro-am partnerships and offer suggestions on how these should evolve in the future.


Looking forward to a fruitful session,

Hi Guys some of us have had fair to good seeing here in Southern UK during this spell of warm weather.  Transparence has been very poor with FPS down to a third of normal.

 

Seeing was better on the 22nd than on the 21st . There are some spots visible on the 22nd more easily seen  in the white light image, where no filter was used at all, just anti dispersion prisms to combat the low altitude dispersion.

¤·····Subject: Venus night-side imaged 2012 May 23

Received; 24 May 2012 at 00:45 JST

Here I have copied the technique of various other observers in imaging  in the night side of Venus by massively over-exposing the thin crescent using an IR longpass filter when Venus is low in a twilight sky. The filter is an Asahi filter which passes wavelengths above 990nm. It therefore gives an exposure sensitive to the window in Venus's atmosphere at 1000nm that transmits the night time thermal glow from the surface.

Unfortunately nothing can be deduced from this image because Venus was passing behind a hedge and a tree as seen from my observatory at the time, so multiple diffraction effects are present. The spots are due to hot pixels (no dark frame was applied). The obstruction situation is unlikely to improve during this elongation. But I have at least established that the thermal glow can be detected with my equipment.

Dear Masami and Masatsugu,

I have attached a set of images of Mars from 20 May.  The images show bright
clouds over Hellas and perhaps some delicate clouds on the morning
terminator and over Isidis.  The NPC also shows the Chasma Boreale or Rima
Borealis rift and also a large dark streak which I believe is exposing
Olympia Planitia and separating the NPC outlier Olympia from the NPC.

Dear Masatsugu : I didn't caught that you were not a member of the OAA anymore. Surely in the process, we'll be able to correct this !


In the meantime I'm still thinking about ISMO notes. Here is a short, partial, update on what I have in mind :
1) The mid-spring orographic cloud over Alba Patera (it gets bigger than the other volcanoes, and much earlier in the season, before fading in late spring). This will introduce the transfer of water vapor from the NPR to the mid-latitudes that is the main thing to know,
2) The cloudless northern hemisphere, a note that deals with the same topic and makes a transition to late spring
3) Something about the ECB, that only appears when the summer hadley cell is getting set from mid spring (perhaps it goes with 2) I think)
4) Tharsis I : morning radiation fogs (cf the abstract)
5) Tharsis II : higher terrains free from fog (Alba Patera and co) that appears as dense reddish areas
6) Tharsis III : the orographics.
7) Frostening of Argyre
8) Frostening of Hellas
9) Something on the polar cap
10) The high altitude cloud (W.Jaeschke)
Elysium is missing on the list or any smaller phenomenon, the bluish
Syrtis Major... do you see anything more ?

Best wishes,

Dear all, and especially our Japanese friends.

Although I did not stop making drawings of Mars, including for this opposition, I am getting more and more overwhelmed by my (astronomical, too) job, plus trips at distance places to view Venus transit or eclipses...
And I did not find time to say that I am right now in Japan, and until the 25th of May.　I have been in Niigata since monday (the 14th) for a "Asteroids, Comets, Meteors" meeting with about 400 participants.
I will travel to Tokyo Sunday evening for the annular eclipse of Monday (21st) morning, and visit Kyoto on the 22nd to 24th.
I am very sorry that Dr Minami can no longer send us the printed version of the CMO/ISMO and I am very thankful for what he did for a long time, and I always appreciated receiving it in my mailbox - although I did not take enough time to send my contributions.

Hi Guy I have a new web site type.

 

As you know I normally add the image files to the e- mail , but this time I have just included a link to the May album slide-show , so you have one click armchair viewing.

 

http://www.david-tyler.com/image-gallery/?wppa-album=28&wppa-slide&wppa-occur=1

 

If you are feeling energetic , you can do a couple of CRTL + clicks to enlarge the page view, or, if you want a longer more detailed look at a particular image, just stop the slide-show on the image and click it again for the original full size view.  

 

If this all works as I hope please let me know, or indeed if it does not !.

Dear Masatsugu,

 

Good to hear from you and thanks for your comments about the strange mushroom on Mars video I managed to capture.  I remember thinking that night that is would just be another night of imaging Mars as it quickly receded from us during the final portion of this apparition. It just goes to show you how many surprises Mars still has in store for us!

 

I'm still hoping to get in a few more imaging session before Mars gets below the trees in my backyard.  The forecast is for clear skies later this week so maybe I will have some more images to contribute to the gallery by this weekend.

 

I wish you the best and I hope you are doing better.  Thanks again for your kind comments.

Dear colleagues,

Mars insists on getting smaller and making life more difficult for us...

Here are two snapshots from May 6 and 13 and you can see clearly the decreased disk diameter between the two dates. May 6 brought me Syrtis on the evening side with a blue cloud and an NPC with cloud patch on its morning side. May 13 brought me just the opposite in terms of disk positions, plus an Elysium orographic (?) cloud. In both cases, Hellas was bright cloud-filled.

Last night I observed Venus visually and via CCD in a dark blue sky (it's now too close to the Sun to be observed against a black sky at reasonable altitude), looking for any illumination of the dark side, but saw none. With CCD I tried with every colour filter and none, monitoring the overexposed image for any sign of the Ashen Light. Here is the IR 742nm image. Seeing was poor.

Received; 12 May 2012 at 22:49 JST

Chile charges suspect with Japanese astronomer murder

Mr Morita was as astronomer of global renown
A Chilean man has been charged with the murder of Japanese astronomer Koichiro Morita in Santiago earlier this week.
Prof Morita, 57, was part of an international team involved in building the Alma radio telescope facility in northern Chile.
He was found collapsed outside his apartment in Santiago last Monday and died hours later in hospital.
Christopher Quijada, 25, is accused of killing him during a street robbery in the early hours of the morning.
Initially it was thought Prof Morita died as a result of an accidental fall, but an autopsy found he was struck on the head with a heavy object.
The authorities say Mr Quijada has confessed to tripping him over as he tried to escape being robbed, causing him to hit his head on the pavement, but denies murder.
The suspect will be held in custody while the investigation continues.
If convicted of robbery and homicide he faces a minimum of 10 years in jail.
Koichiro Morita was a leading figure in creating the Alma Observatory in the Atacama desert in northern Chile.
The Observatory said it was "saddened and deeply shocked" at the news of his death.
"He was one of the proponents of Alma as a global collaboration, bringing together people from all over the world to make what was just a vague concept into a reality," observatory director Thijs de Graauw said.
The giant radio telescope will enable scientists to gaze deeper into space than ever before and may shed light on the formation of our universe more than 13 billion years ago.

Dear Reiichi,
No it's my turn to apologize because I have forgotten to answer to this mail !
Thanks for the delicate drawings. I did notice as well the change of brightness as Hellas proceeds to the limb, but so far I have no answer to give, and I have just not started to study the case (I'm currently working on the Tharsis morning clouds).
As to know if the ground of Hellas is frosted or cloudy, it will be as well hard to answer, just first because both clouds and frost are certainly present. I don't feel that multispectral analisis would help much here ; I'd rather try to consider for example :
- the albedo of the white area. Clouds are bright, but frost may not be bright, as the angle of sunlit is low. Here we may make a parallel with the aspect of the NPC before vernal equinox Ls 0°(like in 2007), where the cap was dull but the last NPH clouds brighter.
- Inside Hellas there is a higher plateau that looks to frost later, or to be less cloudy ; do we see it or not ? (See DPc on 1st april : it is visible). But by the way, we may encounter the case that the basin can be partially frosted, not fully)
- Can we look for indirect clues ? I'm thinking about the "escaping cloud" at the west of the basin. This cloud could be stronger, or even only visible when, the basin starts to frost. It seems to born because a dominant wind carries cold from Hellas. At high HST or probe resolution, small craters under this cloud are covered by frost as well.
Just a few thoughts !

Dear Masami and Masatsugu

I exploit your contact since a colleague of mine, astronomer in Paris
(Thomas Widemann, in cc), is preparing an expedition to Japan for the
observation of the transit of Venus, in the frame of a scientific
experiment (http://venustex.oca.eu).
The problem is, that he cannot easily find telescope facilities in the
north of Japan (Hokkaido). In fact the idea would be to install a 10cm
refractor (especially equipped) on an existing mount. This instrument is
lightweight but a good tracking mount, well set up, is needed (so a
fixed mount is preferred).
Are you aware of any suitable site in that region? If yes, please let us
know at your earliest convenience...

 It was a welcome sight after all the rain we have had during this drought. Yes we are on hosepipe bans just now !.  UK seems to be on a big hill so when it rains most of the water runs into the sea before we can capture it, such a pain , but not before it floods hundreds of homes!  I sure some jobsworth will point out they should not be using a hosepipe to pump the water out of the house.

Dears,
Saturn under degrading seeing:

By pushing the processing, some spots could be guessed in NTrZ and NEB.

The seeing was bad.
The transparency was fair.

Dear Masami,

Sorry to send you yet another animated GIF of the protrusion, but I noticed the last GIF I sent had some problems when being displayed with Apple Safari on some mobile devices.  I have fixed those problems and I also enhanced the frames slightly to improve the visibility of the protrusion.  I also added the central meridian data for each frame for convenience. You may replace the original one I sent with this new one. 

I had some problems with some of the color frames so I am afraid I will not be able to send you a color version of the animation as I promised.

Thank you for your help. Just let me know if you have any questions.

Sincerely,

Hi all,

 

Some decent seeing even at 32° altitude last night. Saturn resized 1.5x, just about resolved Enke's division. couldn't resolve any storm features though.

 

best regards

Hi Guys we had a rare clear break from these April / May showers, with a bit of useful seeing too. Image is x 240% as it was taken at my "SATURN "mag which is set up nicely just now but a bit less than previous Mars captures.

 http://www.kwasan.kyoto-u.ac.jp/~cmo/cmons/2011/120501/DTy01May12.jpg

 

 Dropping down hopefully to Saturn at 21 degrees lower, at 28degs alt., proved to be futile as the seeing was just plain ugly ! I was soon put out of my misery by "those clouds" that just form rather than arrive.

¤·····Subject: Yesterday's Cassini Flybys of Enceladus and Dione

.Received; 4 May 2012 at 04:04 JST

 

May 3, 2012
Dear Friends and Colleagues,

Yesterday, Cassini successfully completed it last close flybys of
Enceladus and Dione for the next three years.  Cassini flew within 50
miles of the south polar surface of Enceladus to allow a measure of the
gravitational signature of that region ... information that will be
vital in deducing (or not) the presence of a  body of liquid water, the
`holy grail' and source of fascination of this moon, buried beneath its
south pole.  And we imaging scientists caught the last, really good look
that we'll ever get in this mission of the jets erupting from the
prominent fractures crossing the polar cap.  With the advent of winter
in a few years, Enceladus' south pole is rushing headlong into darkness
and soon the jets will no longer be visible.

As for Dione, the bounty of images collected yesterday, some with
details as small as 175 feet, is utterly spectacular.

Visit  ...
http://www.ciclops.org/view_event/173/Enceladus_and_Dione_Rev_165_Raw_Preview

... and see for yourself.

Now, we're on target for a May 22 flyby of Titan that will pitch us
poleward, out of the equatorplane into significantly inclined orbits,
for 3 years' viewing of the rings and the polar regions of the planet.

As I've said for years now, this is exploration at its finest.  It won't
continue forever.  So, enjoy it while it lasts!

Best,

Hi Guys This was an interesting morning, with a flare taking place in AR 1471, and two coronal loop prominences, I imaged the larger one only.

 

The flare animation is 9 frames and runs from 10:27 to 10:36ut

Hi,

Here is my last Mars of the apparition, in moderately poor seeing on 10th April. 

 Hope to put a Mars albedo map together for this apparition in due course.

.Received; 2 May 2012 at 21:16 JST

 

Dear Dr. Minami, Christophe,

I have downloaded a new driver software from the site of the maker for my scanner, and now it works out well, so I am attaching here my latest drawings of Mars which I could finally take after almost whole a month(!) of depressive weather.
 The red planet has shrunk a bit, but the gradual darkening along the dawn terminator gives a fantastic 3D-like shadowed spherical appearance (I just like it!).
 I'd like to direct you, Christophe, a naive question: “Is Hellas presently frosty?  or cloudy or both?” …Lately Hellas looks dim in the morning along the terminator, then it seems to be getting brighter as it proceeding easterly to be most bright near the evening limb…How come it goes like that?　…Is it just an influence of the illumination/terminator-darkening?  Or is it related to the daily repeated cloud formation over the area? …With our instruments' spatial resolution for the smaller apparent size of Mars, is it possible to tell what is covering Hellas, ice crystal cloud? or a thin coat of frost? (visually/including observing well-balanced RGB images, or by analyzing IR,R,G,B,UV components' findings).

Hi All,
I have attached some RGB and UV Mars images from 26 April.
The orographic cloud over Arsia Mons was not visible, although the
clouds over the other great volcanoes were fairly  prominent. During
southern late spring and summer, the Arsia cloud is often the first
to appear and is very prominent -- as in the 2003 apparition.
The NPC was tiny with the outliers Lemuria (Olympia) and Ierne still visible.

Dear Masami,

I have attached a set of images of Mars from 25 April.  The images show bright clouds over Olympus Mons and the Tharsis Range.  Also there appears to be a protrusion on the morning limb around Longitude 213W and Latitude 44S at a location very near the earlier protrusion reported by Wayne Jaeschke back on March 20th of this year. 

 I have also attached an animated GIF that shows how the protrusion was consistent in luminance frames taken over a period of 19 minutes. I boosted gamma to a value of 2.5 on the four frames that make up the animation to enhance the visibility of the
protrusion on the morning terminator.

Please give my regards to Masatsugu. Tell him that he has been in my
thoughts lately and I am hoping that he is making some progress with his
recovery.  I think back many times to the wonderful trip to Paris/Meudon in
2009 for the IWCMO Conference and how much I enjoyed meeting him there.

Hi all,

Some belated images from April 1st. Seeing was very good. Hellas looks brilliant with a notable weak equatorial cloud band across the disk.

This set makes a great comparison with and image set obtained exactly one month before in excellent seeing:
http://www.damianpeach.com/mars1112/2012_03_01rgbs.jpg

Note how Hellas only had a few wispy clouds over it the month before. NPC is also larger with no rift visible. Also interesting how much difference the extra 1.4" of diameter makes to the image scale and resolution.
