Interpretation of the Gravitational Anomaly Observed During the March 9, 1997 Experiment

Key Points

This research aims to interpret the gravimetric anomalies observed during a solar eclipse and explore their implications for gravitational interactions.
Analyzed gravimetric data obtained during a total solar eclipse.
Examined temporal characteristics of the anomaly during the active phase.
Determined geometric characteristics related to the shadowing object, the Sun.
The active phase of the anomaly lasted approximately 4 hours, twice the visual contact duration.
The effective spatial scale of the shadowing object was found to be about 2.5 times the Sun's visible diameter.
The analysis suggests the solar corona may affect gravitational interactions through shadowing or lensing.

Abstract

This paper proposes an interpretation of gravimetric data obtained during a total solar eclipse (arXiv:1003.4947v1). Considering the observed anomalies, the active phase (≈ 4 hours) is nearly twice as long as the interval of visual contact (≈ 2 h 16 min). Based on the analysis of temporal characteristics and anomaly shape, an explanation within known physical considerations is proposed, and the geometric characteristics of the effective spatial scale of the shadowing object (the Sun) (≈ 2.5 times the visible diameter) are determined. An interpretation is proposed in which the solar corona is treated as a partially transparent medium capable of modifying gravitational interaction through shadowing, refraction, or lensing effects.
