European Crystallographyc Meeting
The flagship of ECA activities is the European Crystallographic Meeting (ECM), held every year, except when there is an IUCr Congress. The ECMs are the main meeting point for crystallographers in the ECA area to show their recent research. Microsymposia at ECMs are proposed and organized by ECA SIGs.
The ECMs are the general meetings of the ECA and are held every year when there is no IUCr congress.
