¤····Subject: Venus and Mars 15th March 2017

Received: 17 March 2017 at 07:47 JST



Yesterday afternoon a lovely break in the long period of cloud we have been having, combined with decent seeing conditions, allowed imaging of Venus in IR light just 10days before inferior conjunction - showing it as a slender crescent. Venus lay directly above the sun and the bowl facing directly up from the horizon was a wonderful sight in the eyepiece. Later I managed with some luck to locate diminutive Mars at 4.4" across clearly showing Solis Lacus and a very small SPC.


Details are on the images which can also be seen at the top of this page;

Dear Mr. Minami,

I am writing to wish you a complete return to health. I am sorry you are not well. I have been an admirer of your excellent work on Mars for many years and am hoping you can return to observing the planet Mars soon.

Respectfully yours,




iMyron WASIUTA is an old friend of our CMO, -Also he is an acquaintance of Sam WHITBY).

Dear Masami and Masatsugu (and Reiichi),

Thank you for the latest edition of the CMO. Thank you also for your ongoing dedication to recording Mars observations from around the world.

As you would have noticed, there have been a few contributing factors to me not submitting further images (weather, seeing conditions, problems with IR imaging, lower elevation of Mars, etc). I have resolved the IR issue, but it is unlikely that I will be able to submit further during this apparition with Mars becoming low from here.

I was very sorry to hear of the ill health of Masatsugu, and I wish him a speedy recovery, with better health in the future.

I look forward to the next Mars apparition with great excitement and anticipation as it will be particularly well placed for observation from my location.

In the next few years, I would definitely like to visit the Lowell and Harvard observatories in the USA specifically because of the Mars heritage and history that they have. If there are any specific people in the ISMO/CMO that are associated with, or closely connected with these observatories, I wonder if I can be given the contact details (I am thinking maybe of Bill Sheehan as a start?).

It has been exciting for me to discover and visit the Mars heritage and History at the Boyden observatory here in South Africa, as well as the Lamont-Hussey Observatory that has now been converted to a planetarium.

Very best regards,


Clyde FOSTER (Centurion, SOUTH AFRICA)

Hi David,
Excellent work. The dark patches correspond to Beta and Phoebe Regio (in green/orange in the relief map). Violet areas are lower areas so this is where the thermal signal is expected to be at its brightest.

Thanks. I really appreciate these images. If anyone else has been successful in obtaining similar images of the night side of Venus in the near IR this apparition, I would very much like to receive them.
With best regareds,

I've had some success in imaging the night side of Venus in infra-red. Some small contrasts are shown after sharpening and comparison with the relief map suggests the darker areas may correspond to the depressed areas of Sedna Planitia and Guinevere Planitia (purple areas in the relief map), though I am cautious about this conclusion on the basis of this data, as the stack is only about 100 images.

Hi Guys a clear day at last and a solitary sunspot AR2638, along with a nice prominence. Even in the jet-stream hot zone there were moments of fair clarity.

Dear CMO/OAA-team !

Here is a Mars observation from
15th February 2017.

It was taken by my friend Franz Klauser (FKr) using his 15"Newtonian located in Puchenstuben/Lower Austria.

Thank You in advance for displaying his picture on the CMO page !

best regards

Another lucky break in the generally cloudy weather on a Saturday afternoon again allowed an early set-up and imaging of a huge Venus and a tiny Mars around sunset with reasonable seeing conditions prevailing.


I must say that having Venus close to Mars makes hunting it down in a bright sky a realistic possible for my non GoTo Dobsonian- without Venus's beacon-like presence close by finding Mars around sunset would not be a practical proposition.

¤····Subject: Re: Mars 19 February R filter

Received: 20 February 2017 at 23:05 JST


Thanks, Roger
Yes, it certainly looks like it was a rather tame apparition, at least compared with the 2nd half of the previous one, where I was able to pick up a number of local dust storms, and which got me off to an exciting start in Mars imaging! However, I guess that the passing of another relatively quiet apparition raises the probability of us having major activity on the next one......
If I recall, the dust storm season will fall closer to opposition in 2018, so I guess that could be a good or a bad thing... It would certainly be exciting to capture hi-res images of the initiation and development of a planet-encircling storm, but I can imagine rather frustrating to image a relatively featureless Mars week after week... :-).
Thanks again for all the interaction over the last while.
Best regards,


Clyde FOSTER (Centurion, SOUTH AFRICA)

Thanks, Clyde. I agree with your assessment.

It looks as though another apparition has passed without at planet-encircling dust storm. The latest onset of a planet-encircling dust storm was Ls 312. It's now Ls 321, so it would be unusual for one to start now.


Thank you for your conscientious and helpful observations through the dust season!

Hi all,

Unfortunately afternoon conditions remain very poor. Attached is a rather poor R filter image. However I believe there is sufficient data to be able to confirm that Syrtis Major and Sinus Sabeaus are still detectable. Hellas is also detectable, and appears gnormalh, in my opinion.  Ls 320 and 4.7h.

Best regards,

Dear all,

The professional conference European Planetary Science Congress (EPSC) will be held from September 17 to September 22, 2017 in Riga, Latvia

Meeting webpage:

We would like to draw your attention to the AM1 session "Amateur collaborations in small bodies, terrestrial, giant and exo planets professional studies" and the AM2 session "Juno Ground-Based Support from Amateurs", in the program group "Amateur Astronomy". Both sesions are convened by amateur astronomers together with professionals. We would like to invite you to attend or actively participate to these sessions by contributing a paper and/or meeting and exchanging views and ideas with other amateur and professional astronomers studying the solar system (planets, asteroids, comets, meteors, ...) and exoplanets, and in supporting the Juno mission.

For contributing, please fill in the abstract submission form that you will find at the meeting web page above (abstract deadline: May 3, 2017). Contributions will be oral talks and poster contributions. The language at the meeting will be English for all presentations.

Please note that this year EUROPLANET-2020 will provide budget to support amateur participants from European countries. This budget will be allocated to participants considering the scientific value of their expected presentations and promoting diversity of participants from different countries. Note also that amateur participants will not have to cover registration fees.

Please feel free to circulate this message to all those who might be interested in the event.

Looking forward your contribution or participation to EPSC2017,

Marc Delcroix, Ricardo Hueso and the co-conveners of the EPSC2017 AM1 and AM2 sessions.
