    Merci, c''est cool je n'avais pas encore fait cette année ces longitudes martiennes, qui sont carrément sympa avec pas mal de détails
  2. Mars le 29 novembre 2020

    Bonjour à tous, Mars par seeing pas mal, malheureusement des problèmes techniques ont écourté ma session ... En tout cas j'ai pu avoir une très belle vue de Valles Marineris er Solis Planium au méridien, les trois volcans de Tharsis se lèvent proches du terminateur. RVB: Images bleues: Bons ciels,
  3. Bonjour à tous, Grosse session ce soir là, où j'ai pu profiter d'un seeing plutôt bon. Une jolie vue de Terra Sirenum dans l'hémisphère Sud, la calotte polaire australe, et au Nord d'Amazonis Planitia et de l'étendue du volcan Olympus Mons, et sa caldeira. L'image bleue de 21h54 a une belle définition, et sur l'animation dans le bleu ont voit dans l'hémisphère Nord au terminateur une formation de haute altitude. RVB: Version réhaussée de 50% d'infrarouge pour les détails: Deux infrarouges: La bleue la plus résolue: L'animation de 6 images bleues: Bons ciels,
  4. Bonjour à tous, Des conditions plutôt bonnes, qui m'ont permis de voir la tempête de poussière arriver sur Elysium et Arcadia Planitia. La petite calotte polaire australe est bien visible, ainsi que le voile boréal. L'infrarouge, avec pas mal de fin détails, notamment Olympus Mons, touché par la tempête semble t'il sur les images suivantes RVB: Version RVB dopée à l'infrarouge pour prétendre faire des meilleures images : Version RVB pure, la tempête est bien mieux visible: Une bleue, la seule pour laquelle j'ai réussi à avoir un meilleur résultat avec Astrosurface, et je trouve que c'est un beau résultat. On voit une petite excroissance sur le terminator qui est peut-être un petit nuage: Et une bleue bande plus étroite: Les images du lendemain sont en cours de traitement, un cran au-dessus niveau qualité! Bons ciels,

    Tu as raison Lucien, c'est bien mon approche. Sans compter que qui ne tente rien n'a rien, je trouve quand même que récemment j'arrive à avoir de temps en temps de bien bonnes conditions ... Et l'avantage de ma config non fixe, c'est qu'une fois que je l'ai préparée, je préfère prendre quelques images plutôt que de la redémonter et me dire que ce que j'avais fait n'a servi à rien

    Mars par conditions bien moyennes, Terra Cimmeria au Sud avec la calotte polaire australe de glace de dioxyde de carbone, et au Nord Elysia planitia bien homogène , avec au Nord le voile polaire boréal: Image infrarouge: RVB: RVB dopée aux infrarouges (moyennement efficace pour cette session ): Bons ciels,
  7. Mars le 12 novembre 2020

    Merci à tous! C'est vrai que j'étais content de voir Mars comme cela après la Jupiter toute pourrie de début de soirée, comme quoi faut insister
  8. Mars le 12 novembre, excellent seeing

    Sous WinJupos, utilises bien le contour avec détails graphiques dans l'ajustement, il faut bien caler le relief sur ces détails. Je passe un certain temps à faire ce "calage" initial sur une bonne image avant de me lancer dans le traitement de dérotation
  9. Mars le 12 novembre, excellent seeing

    Salut Daniel, Excellent travail, bravo!
  10. Mars le 12 novembre 2020

    Bonjour à tous, Une Mars qui s'en sort correctement dans l'infrarouge, ou une zone d'albedo très claire apparait dans Elysium Planitia: Colorisée (en gardant 50% de la luminance couleur) : C'est intéressant de voir la différence avec la couleur pure, malgré sa résolution plus mauvaise, celle -ci mets bien plus en valeur le voile polaire boréal et les nuages matinaux au terminateur : Et une bleue bande étroite! Bons ciels,

  14. Message plus détaillé en anglais: Dear all, We are a few weeks before the Europlanet Society Conference (EPSC) which this year is fully online. EPSC has a long tradition to join amateur and professional astronomers with dedicated sessions on amateur astronomy and collaborations of amateur and professional astronomers. This challenging year we miss the oportunity to have both communities together in the same city discussing on exciting observations and sharing personal experiences. However the meeting organizers together with amateur astronomers deeply involved in EPSC past meeting have worked to have the largest amateur astronomy program ever produced in this meeting. Here is a list of events that you may like to consider to join. Splinter meetings do not require registration on the conference and will be mostly organized using Zoom. Keynote lectures will be publicly availalable as video lectures on Vimeo after the conference. Some of these events go outside topics generally discussed in this email list but please send information about them to amateur astronomers that could be interested to join those events on topics such as exoplanets, the Europlanet Telescope Network or the keynote lecture by Marc Delcroix that will cover the broad spectrum of professional and amateur collaborations in solar system astronomy. MESSAGE INDEX: ----------------------------------------------------------------------------------------------------------------------------------------------------------------- 1- Splinter meeting: Juno-Ground Based Support from Amateur Astronomers, Mon 21 September (18:00-20:00 CEST) 2- Session showcase: Professional-Amateur collaborations in small bodies, terrestrial and giant planets, exoplanets, ... Wed 23 September, 11:20-11:40 (CEST) 3- Keynote lecture by Marc Delcroix: The growing extent of professional and amateur collaborations in planetary sciences, Tue 29 September, 17:00-17:20 (CEST) 4- Splinter Meeting: The Europlanet Telescope Network, Wed 30 September, 14:00-16:00 (CEST) 5- Splinter Meeting: The Ariel mission for exoplanets and support from amateurs, Mon, 28 Sep, 18:00–20:00 ----------------------------------------------------------------------------------------------------------------------------------------------------------------- Detailed information on each event below. Links to some of these events are already available in this email and others will appear in the meeting website in the next few days. ----------------------------------------------------------------------------------------------------------------------------------------------------------------- 1. SMW2: Juno Ground-Based Support from Amateur Astronomers 21 sep 2020 18:00-20:00 (CEST, París) | Expected duration: 1hr45 min. ----------------------------------------------------------------------------------------------------------------------------------------------------------------- https://meetingorganizer.copernicus.org/EPSC2020/session/38663 This event does not require registration on the meeting. The Juno mission orbits Jupiter since 2016. Its JunoCam instrument is providing the highest resolution images of the planet ever obtained. To understand the temporal and spatial context of these images and the details of Jovian meteorology Juno relies on a global ground-support from professional and amateur astronomers. This collaboration has proven essential to the interpretation of this outstanding data. Amateur astronomers provide images that are used to plan the high-resolution observations from JunoCam and citizen scientists process many of the astonishing high-resolution images obtained by JunoCam contributing to the success of the mission. The splinter will contain talks, questions and a short round-table at the end and is open to Juno scientists, amateur astronomers and citizen scientists collaborating with the Juno mission. The splinter will be recorded and available online after the conference. Splinter meeting Program: - Jupiter image processing. Christopher Go - Recent meteorological events on Jupiter. John H. Rogers (BAA) - The Juno mission. Glenn S. Orton (JPL) - JunoCam on Juno. Candice Hansen (PSI) - Junocam image processing. Kevin M. Gill - The value of long-term Jupiter data. Arrate Antunano (Leicester University) Time: 21 sep 2020 18:00 (CEST, París) | Expected duration: 1hr45 min.

SMW4: The Europlanet Telescope Network Wed 30 September, 14:00-16:00 (CEST) ----------------------------------------------------------------------------------------------------------------------------------------------------------------- https://meetingorganizer.copernicus.org/EPSC2020/session/38665 This event does not require registration on the meeting. As part of the recently launched Europlanet 2024 Research Infrastructure, a new collaboration between telescopes around the world has been started for providing coordinated observations and rapid responses in support of space missions and in following-up of new events. The so-called Europlanet Telescope Network (bit.ly/37SCiyj) will thereby provide professional scientists and amateur astronomers with access to an initial set of 16 telescope facilities. Scientists and amateurs can now apply to visit those facilities (see website: bit.ly/2Br5LDt). The Europlanet Telescope Network further plans to support the integration of amateur astronomers into planetary sciences, since their observations can be of crucial importance for several scientific areas. The Splinter Meeting will give an overview on the network, the involved telescope facilities, and will discuss support for amateur astronomers in Europe and beyond. The meeting is open for everyone interested in the Europlanet Telescope Network! ----------------------------------------------------------------------------------------------------------------------------------------------------------------- 5. SMW12: The Ariel mission for exoplanets and support from amateurs Mon, 28 Sep, 18:00–20:00 ----------------------------------------------------------------------------------------------------------------------------------------------------------------- https://meetingorganizer.copernicus.org/EPSC2020/session/38673 This event does not require registration on the meeting. More than 4000 exoplanets have been discovered so far, and this number is still growing rapidly! However, we know very little about them: What are they made of? What are the conditions there? How did they form and how did they evolve? ESA’s M4 mission, Ariel, will observe spectroscopically around 1000 exoplanets to further characterise their atmospheres and try to answer these questions. Exoplanets is one of the few fields that amateur astronomers and the public can contribute significantly, with observations with small and medium scale telescopes. I the case of Ariel, small and medium size telescope are valuable, in order to plan the observations as efficiently as possible. To achieve this, a good knowledge of the planets’ ephemerides is needed before the launch of Ariel in 2028. While ephemerides for some planets are being refined on a per-case basis, an organised effort to collectively verify or update them when necessary does not exist. In this session, we will present the Ariel mission and will introduce the ExoClock project, an open, integrated and interactive platform with the purpose of producing a confirmed list of ephemerides for the planets that will be observed by Ariel. The project has been developed in a manner to make the best use of all available resources: observations reported in the literature, observations from space instruments and, mainly, observations from ground-based telescopes, including both professional and amateur observatories. To facilitate inexperienced observers and at the same time achieve homogeneity in the results, we created data collection and validation protocols, educational material and easy to use interfaces, open to everyone. ExoClock was launched in September 2019 and now counts over 160 participants, mostly amateur astronomers, who’ve already observed 1200 transits for 170 exoplanets. The session will start with Giovanna Tinetti from UCL, the Principal Investigator of the Ariel Mission, who will present the concept and the goals of the mission and will continue with Athanasia Nikolaou from Sapienza who will present the prospects of Ariel for small planets. Next, Anastasia Kokori from UCL, coordinator of the ExoClock project, will share the scope and the principals of the ExoClock Project, while Martin Crow, an active ExoClock observer form the British Astronomical Association, will share his experience from observing exoplanets and participating to ExoClock. Finally, Angelos Tsiaras from UCL, coordinator of the ExoClock project, will demonstrate how to analyse exoplanet observations with the dedicated, user-friendly tools developed for the project. The ExoClock project website: www.exoclock.space Educational material can be found at: www.exoworldsspies.com Splinter meeting agenda: - The Ariel mission. Giovanna Tinetti - Planetary Perspectives of Ariel: Looking at the tree and adding the forest. Athanasia Nikolaou - The ExoClock project: How amateurs can contribute to Ariel. Anastasia Kokori. - Experiencing ExoClock with an active participant. Martin Crow - Analysing exoplanet observations.
