Abstract: | By using a high-precision LaCoste-Romberg (D-122#) gravimeter, continuous and precise measurements were carried out during
the March 9, 1997 total solar eclipse in the 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
has been found. However, there are two ‘gravity anomaly valleys’ with near symmetrical decrease of about 6–7 μGal at the first
contact and the last contact. This is the anomaly phenomenon observed and reported for the first time in the literature. This
note presents some analyses and discussions. |
