Abstract: | By using a high-precision LaCoste-Romberg gravimeter, continuous and precise measurements were carried out during the March
9, 1997 total solar eclipse in Mohe region in Northeast China. The gravity variations were digitally recorded during the total
solar eclipse so as to investigate the possible anomaly of the Sun and the Moon's gravitational fields on the Earth. After
the careful processing and analysis of the observed data, no significant anomaly during the very solar eclipse was found.
However, there are two ‘gravity anomaly valleys’ with near symmetrical decrease of about 6 ∼ 7 μg at the first contact and the last contact. This is the anomaly phenomenon observed and reported for the first time in the
literature. This paper is intended to explain the observed anomaly by conducting the tilt experiment due to the thermal stress
and temperature change in the solar eclipse. A new constraint limit on gravitational shielding is thus obtained. Some analysis
and discussions are presented although further studies and research are highly needed.
This revised version was published online in July 2006 with corrections to the Cover Date. |
