The variations of gravity were measured with a high precision LaCoste-Romberg D gravimeter during a total solar eclipse to investigate the effect of solar eclipse on the gravitational field. The observed anomaly (7.0 ± 2.7) × 10^-8 m/s^2 during the eclipse implies that there may be a shielding property of gravitation.
