The Large Volume Detector LVD (Gran Sasso National Laboratory, Italy) is a neutrino scintillator observatory monitoring the Galaxy since 1992, searching for low energy neutrino bursts from gravitational stellar collapses. We present the status of the detector that reached its final active mass of 1000 t in 2001. No candidates have been detected over all the fifteen years of observation: the resulting 90% c.l. upper limit to the rate of gravitational stellar collapses in the Galaxy will be presented.
