Abstract: The interferometric gravitational wave detector Virgo has successfully completed the first major step of its commissioning. It consists of a Michelson interferometer with 6 m arms with suspended mirrors. The interferometer is tuned to the dark fringe with a recycling mirror on the other port (bright fringe) to form an equivalent 12 m long Fabry-Perot cavity. This setup has allowed us to validate the major technology choices that have been made: passive seismic attenuators, a light source with a long mode cleaner, many analogue and digital servo loops, control software, high speed data acquisition system. A sensitivity of 8 x 10(-17) M HZ(-1/2) at 1 kHz together with a duty cycle of 80% has been attained during a 72 h engineering run. The data analysis allowed us to understand the noise contributions, and several improvements have been carried out while proceeding with the end of the installation of vacuum tubes and the remaining suspensions, and before starting the commissioning of the 3 km long Fabry-Perot cavities.
