Dear colleagues,

You are reminded that the deadline for submitting Letters of Intent (LoIs) for 2025 IAU Symposia is the 15th of September. You are advised to read carefully the Rules & Guidelines for IAU Scientific Meetings before the preparation of an LoI.
Note that submission of an LoI is not obligatory, but it is strongly recommended. LoIs received by the deadline are posted on the IAU website to facilitate collaboration. The IAU places emphasis on obtaining a balanced program of meetings, scientifically and geographically. Past IAU symposia and future accepted symposia are listed here and here, respectively. You may also wish to consult the list of Focus Meetings accepted for next year's GA.
The IAU looks forward to receiving your LoIs.

Best regards
IAU Assistant General Secretaty Diana Worall
