Present status and future directions of Onsala Space Observatory, Sweden

Onsala Space Observatory (OSO), the Swedish National Facility for Radio Astronomy, operates a 20m-diameter millimetre-wave telescope and a 25m-diameter cm-wave telescope at Onsala, Sweden. OSO is also responsible for the Swedish involvement in the Atacama Pathfinder Experiment (APEX), an excellent sub-millimetre telescope on an exceptionally good site, Llano Chajnantor in Chile. Furthermore, OSO is involved in several international projects such as EVN, IVS, LOFAR, ALMA, Herschel and SKA. We will describe the present status of the observatory and outline some of the planned future directions.
