IAU100 Amateur
Astronomy Day Event

On Saturday 13 April 2019 at the Palace of the Academies in Brussels, Belgium, the International Astronomical Union will organise its first event for amateur astronomers. Through a mix of presentations by professional and amateur astronomers, this meeting aims to further build the relationship between amateur astronomers, their organizations and the IAU.

This special event for amateur astronomers will include keynote lectures by prominent scientists, review talks about Professional-Amateur astronomy projects, parallel sessions to showcase the work of amateur astronomers  and panels discussing topics such as what the IAU can do for amateur astronomers. There will also be the possibility for showcasing some equipment as well as visiting the acclaimed Above and Beyond exhibition (, which has been commissioned by the IAU to showcase some of the most significant and surprising astronomical breakthroughs that have shaped science, technology and culture over the last century.

The event is free to attend for any amateur astronomer worldwide, and we look forward to participation from a broad range of countries. Both registration and Abstract submission are now open, and the organization welcomes contributions on by amateur astronomers.


If you are interested in attend the event please register here by 1 April 2019 the latest.


The deadline for abstract submission for the parallel sessions to showcase the work of amateur astronomers is Sunday 10 February 2019. Find more about abstract submission here. The selected contributions will be communicated to their authors by late February.
