Les évènements et présentations orientés amateurs:

- lundi 21/09 18h-20h : SMW2 - Juno Ground-Based Support from Amateur Astronomers

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.

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.
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.

2. ODAA3: Professional-Amateur collaborations in small bodies, terrestrial and giant planets, exoplanets, and ground-based support of space missions
   Tuesday 29 September, 17:00-17:20 (CEST)

Session showcase: Brief summary of talks and abstracts on amateur astronomy presentations (16) submitted to the conference. This event is part of the meeting and requires being a registered participant in the meeting. Talks and posters belonging to this session will be available to the registered participants in the meeting website.

3. Keynote lecture: The growing extent of professional and amateur collaborations in planetary sciences

     Tue, 29 Sep, 17:00–17:20

   Marc Delcroix

This will be a live presentation as part of the plenary programme for EPSC with Q&As at the end of the talk.
This keynote lecture will be recorded and will be publicly available on the EPSC Vimeo channel after the meeting.

4. SMW4: The Europlanet Telescope Network
   Wed 30 September, 14:00-16:00 (CEST)
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 ( 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: 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
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.
