Ventspils International Radio Astronomy Center

Ventspils International Radio Astronomy Centre (Latvian: Ventspils Starptautiskais radioastronomijas centrs – VIRAC) is an ex-Soviet radio astronomy installation 30 km north of Ventspils, Latvia, on the coast of the Baltic Sea in Ance parish. The installation was secret until 1993 after Latvia regained independence. It was taken over by the Latvian Academy of Sciences after the withdrawal of the Soviet Army in 1994. Since then, two of the three radio telescopes have been repaired and renewed.
