observations for correlation, thus allowing astronomers to respond to events as they happen in real time. The VLBI data are streamed to JIVE, where they are correlated and the final, high-resolution image created. In a demonstration of e-VLBI as part of 100 Hours of Astronomy in 2009 14 telescopes from Australia, Chile, China, Finland, Germany, Italy, the Netherlands, Poland, Puerto Rico, Spain, Sweden and the UK participated in joint observations of the active galaxy 3C120. The participating telescopes included: the 26 meter telescope at Hobart, operated by the University of Tasmania; the 22m dish of Mopra, part of the Long Baseline Array, operated by CSIRO; the 25m dish of Sheshan near Shanghai, operated by the Shanghai Astronomical Observatory, Chinese Academy of Sciences; the 14m Metsähovi dish, operated by the Aalto University; the 32m telescope of Toruń; the 32m telescope at Medicina, operated by the Instituto Nazionale di Astrofisica; the 25m telescope at the Onsala Space Observatory; the Westerbork Synthesis Radio Telescope; the Yebes 40m, operated by the Observatorio Astronomico Nacional; the 300m dish of Arecibo, located in Puerto Rico; the 6m dish of TIGO, operated by the Geodätisches Observatorium Wettzell.
