The variations of gravity were measured with a high precision LaCoste-Romberg D gravimeter during a total solar eclipse to investigate the effect of a solar eclipse on the gravitational field. The observed anomaly (7.0±2.7)×10-8 m/s2during the eclipse implies that there may be a shielding property of gravitation.
