AbstractWe show that the microquasar LSI+61degrees 303 is running away from its birth place in a young complex of massive stars. The supernova explosion that formed the compact object shot out the X-ray binary with a linear momentum of 430+/-140 M-circle dot km s(-1), which is comparable to the linear momenta found in solitary runaway neutron stars and millisecond pulsars. The properties of the binary system and its runaway motion of 27+/-6 km s(-1) imply that the natal supernova was asymmetric and that the upper limit for the mass that could have been suddenly ejected in the explosion is similar to2 M-circle dot. The initial mass of the progenitor star of the compact object that is inferred depends on whether the formation of massive stars in the parent stellar cluster was coeval or a sequential process.
