MEASUREMENTS OF GRAVITY CONSTANT AND HELI O-GEOPHYSICAL ELECTROMAGNETIC DISTURBANCES

Results of continuing measurements of gravity constant fry device of O .V.Karagioz - V.P.Izmailov in 1991 were compared with helio-geophysica l disturbance indices. It was found that extreme high values of the co nstant correspond to magnetic activity minimums period. Dispersion of the measurements in various cycles of measuring is smaller for higher geomagnetic activity (A(p) > 30), but the effects of strong magnetic s torms was not found. Also the degree if ionosphere disturbances by the solar chromosphere flares influences on dispersion of measurement res ults. 27-days repetition of the results is expressed feebly. The effec ts, more probably, are caused by amplitude-spectral variations of back ground electromagnetic fields of extra-low frequencies effecting on el asticity coefficient of thread for rotating pendulum suspender because of <<magnetic-plasticity>>.
