Gamma-ray, X-ray, optical or neutrino observations of cataclysmic cosmic events with plausible gravitational wave emission can be used to constrain searches for gravitational waves in LIGO (VIRGO) data. Information on the progenitor, such as trigger time, expected frequency range and direction, can enhance our ability to identify gravitational wave signatures with amplitude close to the noise floor of the detector with a low false alarm probability. Even in the absence of detection, the association of the astrophysical trigger with a particular source distance allows to interpret upper limits on the observed flux of gravitational waves in terms of the energy emitted in form of gravitational waves. After a brief summary of ongoing analyses, I will focus on the limits set by LIGO on gravitational waves coincident with GRB 070201, a short hard gamma-ray burst with possible association with the Andromeda galaxy (M31), and on their interpretation.
