The afternoon included a visit to la grande lunette and reports on remote observatories in Chile and South Moravia.
On 15 May, the sessions covered RR Lyrae stars, CCD surveys, data reduction, exoplanet photometry, and correlations in RRab stars. After lunch, contributions focused on unusual RR stars, Blazhko studies, lowamplitude variations, and the revision of the Priority Stars list.
On 16 May, the symposium concluded with the GEOS organizational session, addressing finances, instrumentation, collaborations, editorial matters, and future symposia, followed by a farewell coffee.
