If Weber's gravitational-wave observations are interpreted in terms of a source at the Galactic center, both the intensity and the frequency of the waves are more reasonable if the source is assumed to emit in a synchrotron mode (narrow angles, high harmonics). Although presently studied sources for such modes are astrophysically unsatisfactory---high-energy, nearly circular, scattering orbits---other possible sources are under study.
Charles W. Misner (Mon,) studied this question.
