VSA, or Visnjan School of Astronomy, is a summer workshop of astronomy located in the Visnjan Observatory, situated in the western part of the Istrian highlands, near the city of Porec, Croatia. It represents a continuing experiment in an attempt to merge scientific projects and high school students' education. Students are treated like research colleagues in the scientific process. Created in the Visnjan Observatory, VSA is the result of many years' efforts of its organizers and founders. In 2010 we hope to maintain the tradition of contemporary topics, scientific discoveries and having a good time.
