Visiting the radio telescopes in Humain (Belgium)

During the weekend of September 9 and 10, it was possible to visit the radio telescopes in Humain (Belgium).  It was the first time since the site was opened in 1953 that a visit was possible.  The station is used by the Royal Observatory of Belgium.  A solar interferometer of 48 radio telescopes was build in the 1960s.  The telescopes are not used anymore since 2001.  All telescopes are have a diameter of 4 meter and are located at a height of 293 above sea level.  

A few larger telescopes are still in use at the site. 

Enjoy the pictures!
