In the first week of December we have tested the local-control electronics on a modecleaner double pendulum. After some minor problems it worked excellent. Once the local-control loop was closed no tilt or rotation of the dummy mirror could be seen. At the site, the cleaning of the central building and the fabrication of a clean tent took place.
GEO 600 has been registered as one of the Projects of the World Exposition EXPO 2000 in Hannover ("Projects all over the World in Germany").
