The CERN Neutrino to Gran Sasso (CNGS) project aims to produce a high energy, wide band \(\nu_{\mu}\) beam at CERN and send it toward the INFN Gran Sasso National Laboratory (LNGS), 732 km away. Its main goal is the observation of the \(\nu_{\tau}\) appearance, through neutrino flavour oscillation. The beam started its operation in August 2006 for about 12 days: a total amount of \(7.6~10^{17}\) protons were delivered to the target. The LVD detector, installed in hall A of the LNGS and mainly dedicated to the study of supernova neutrinos, was fully operating during the whole CNGS running time. A total number of 569 events were detected in coincidence with the beam spill time. This is in good agreement with the expected number of events from Montecarlo simulations.
