Abstract
In this letter we report the results we obtained experimentally demonstrating the feasibility of absolute timing of impulsive gravitational wave signals by means of a resonant bar detector. We reached a resolution of less than 20 μs for SNR ≥ 10. We also discuss the important prospects this result opens for the present and for the future, as a necessary condition for the implementation of a global network of gravitational wave detectors.Keywords
