The Conference on Variable Star Research is the most important meeting organized by Variable Stars and Exoplanet Section of the Czech Astronomical Society. This year, our co-organizer is the Institute of Theoretical Physics and Astrophysics of the Faculty of Natural Sciences, Masaryk University in Brno, who has provided the its premises and technical support for the conference.

Czech Astronomical Society (CAS), founded in 1917, is a voluntary association of professional astronomers, amateur astronomers and interested citizens. Its Variable Stars and Exoplanet Section (VSES) is coordinating variable stars and exoplanet research in the Czech Republic. Its online Exoplanet Transit Database and other online services are used internationally.

The goal of this annual meeting, which will be held for 55th time this year, has always been to create ties between professionals, students and amateur astronomers in the field of variable stars and exoplanet research. Overview lectures by professionals, current research results and methods by astrophysics students and observation results by amateur astronomers are presented every year. Observation techniques, equipment, software tools and online resources are also discussed.

We are responding to current trends of internationalisation of the research field and the growing number of international collaborations by opening the meeting to audience from other countries. We host between 50 - 80 participants from the Czech Republic and neighboring countries as well as, possibly, more online audience.

This year meeting will assume hybrid form - both in person and online via ZOOM application, and will be held in Czech, Slovak and English languages. There will be student section for high school and university students presenting their work on Friday. The student section will be organized as a contest where the best presenter will be recognized and receives price donated by the VSES CAS.

Papers from the meeting will be published in Open European Journal on Varible Stars, an electronic open peer-reviewed journal issued by VSES CAS in cooperation with Masaryk University Brno, with indexation in SIMBAD database and Smithsonian/NASA's ADS. Recordings of the talks will be made public on VSES CAS YouTube channel and presentation files will be accessible in meeting program.
