The IAU is inviting its national members to submit Letters of Intent to host the IAU General Assembly in 2027 (GA2027). This triennial event takes place over 12 days, offering a rich scientific programme and facilitating meetings and new collaborations between astronomers.

The programme includes 6 Symposia and 12 Focus Meetings, which are selected by the IAU Executive Committee. There are also Invited Discourses by distinguished scientists, scientific meetings organised by the 9 IAU Divisions, meetings organised by each of the 4 IAU Offices, IAU administrative sessions, public lectures and a social programme. With a few thousand astronomers from across the world in attendance, hosting an IAU General Assembly is an exciting opportunity for a member state and its local astronomy community.

It is expected that in 2027 the IAU General Assembly will be an in-person meeting. Letters of Intent to host the IAU GA2027 should be submitted by the deadline of 1 November 2020. Further details on the Rules & Guidelines for hosts can be found here.
