Precise measurement of gravity variations during a total solar eclipse

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\ifmmode\pm\else\textpm\fi{}2.7)$$\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}8}$ ${\mathrm{m}/\mathrm{s}}^{2}$during the eclipse implies that there may be a shielding property of gravitation.
