One of the major goals of gravitational wave astronomy is to explore the astrophysics of phenomenon that are already observed in the particle/electromagnetic bands. Among potentially interesting sources for such collaboration are gravitational wave searches in coincidence with Gamma Ray Bursts. On March 29, 2003, one of the brightest ever Gamma Ray Burst was detected and observed in great detail by the broader astronomical community. The uniqueness of this event prompted our search as we had the two LIGO Hanford detectors in coincident lock at the time. We will report on the GRB030329 prompted search for gravitational waves, which relies on our sensitive multi-detector data analysis pipeline specifically developed and tuned for astrophysically triggered searches.
