The topics of the meeting are primarily the astrophysics and astrodynamics of the solar system bodies, stars and galaxies.

The Sub-Regional European Astronomical Committee was established within the framework of the "Enhancing astronomical research and observation in South-East Europe and Ukraine" project of the UNESCO Regional Bureau for Science and Culture in Europe (UNESCO-BRESCE). From the Statute of the Sub-regional European Astronomical Committee: "The main objective of SREAC is to elaborate and implement a sub-regional strategy for the development of astronomy in South-East Europe and Ukraine and to strengthen astronomical co-operation in the sub-region, and between the region and countries outside." This is also the most important aim of the Meeting in September.

We welcome you to Belgrade, and look forward to your participation in the meeting and contributions to the development of astronomy in South-East Europe!
