Solar Eclipse and the Allais Effect
Maurice Allais found deviations of a Paraconical Pendulum during the 1954 Solar Eclipse in Paris, and also in 1959. The deviation was about 15 degrees which is quite substantial. Scientists still have "no idea" of the cause of these observations, but tend to attribute them to natural causes rather than gravitational variability. The deviation found was claimed to be about 100 million times greater than scientific theory would allow.
It appears that Prof Allais has indeed found a gravitational variation. If the Solar Eclipse can create a light filter when the Sun's Dynamic Gravitational Field is disturbed by the Moon, then it seems only logical that the other functions of the Electric Field would also be disturbed, and the effects of centrifugal force would indeed cause the pendulum to realign itself somewhat.
It is a pity that nobody has reported any experiments with weight. It is possible that weight may decrease measurably in the area of shadow.
Check out the diagram on how a plumb-bob would be expected to behave, but does not.
My experiment with a stationary plumb-bob was in fact nothing like Allais's experiments.
His work entailed a swinging pendulum. This changes direction slowly as the Earth rotates
and the alignment with the various gravitational bodies alters. His pendulum took a sudden deviation during the total solar eclipse, of about 15 degrees. It is fairly obvious that the moon must be blocking something, and "modern science" does not want to know.
About 1999 Allais had his findings translated from French to English in the forlorn hope that NASA might revisit his work, but nothing has been done. This is a 3.8 Mb PDF file.
A huge amount of material about Allais and his work is available on the Internet, and is essential reading for anyone interested in understanding, as opposed to ignoring, gravity.
