Call for Expressions of Interest to organise Symposia, Special Sessions, and Lunch Sessions at EAS 2026

The European Astronomical Society Annual Meeting will take place in Lausanne, Switzerland, on 29 June-3 July 2026. The meeting is organized by the European Astronomical Society (EAS). The venue is the SwissTech Convention Centre.

We hereby invite proposals from colleagues who are interested in organising a Symposium, a Special Session, or a Lunch Session at the EAS Annual Meeting 2026.

A broad range of parallel sessions can be accommodated as:

(A) Symposia

which normally consist of up to 6 blocks of 1.5 hours, stretching over 2 days, although exceptionally and in well-justified cases these symposia can be longer,

(B) Special Sessions

consisting of up to 3 blocks of 1.5 hours on the same day.

(C) Lunch Sessions

taking place during the lunch break for 1-1.5 hours on one day.

(D) Special Sessions with a Lunch Session

combining the blocks during parallel scientific sessions and a session during the lunch break on one day (for special purposes, e.g., hands-on session, etc; this option is not to extend the length of scientific blocks).

Proposers should strive to make their proposals of interest to large fractions of the European astronomical community.

Proposers should also indicate that and how they will adhere to the EAS Ethics Statement and Guidelines for Good Practice.

Organisers of EAS Annual Meeting sessions will benefit from the logistical support including the venue, registration handling, the portal for abstract submission and reviewing, and the hosting of a web page on the EAS Annual Meeting website.

Session organisers should not count on financial support from EAS for attending the conference, neither for themselves nor for their invited speakers. Registration fee waivers and/or travel grants will be available on request and treated equally with the other applicants.

There are typically no general EAS Annual Meeting proceedings. The decision to have proceedings for each Symposium and Special Session is taken by the SOC of the individual session, upon approval by the EAS Annual Meeting Board.

Proposals should be sent via an on-line form, by 30 September 2025.

Applicants will be notified around November 2025 about the outcome of the selection.

Individuals within the Astronomy, Solar physics, and Space Science communities are strongly encouraged to propose and organise sessions. Astronomers not connected with any European institution are also welcome to propose sessions, but should plan to involve a European collaborator.
