    Well I just got this in an email.

    Hey, gang:

    For those of you who wondered where things stood on an answer to the
    question of whether Foucault pendulums are affected by forces during a Total
    Solar Eclipse, here's a response I've just received from Dr. David Noever,
    NASA Marshall Space Flight Center. I believe Dr. Noever is the lead
    scientist for the Allais Global Gravity Experiment. A lot of interesting
    stuff here.

    -Thanks for your email which was forwarded to my attention. We are no less
    excited as time passes in the analysis and as we uncover a very extensive
    historical scientific interest in this fascinating and rather mysterious
    question. I can only report that we will discuss any results after going
    through the scientific peer review process. As Professor Allais indicated
    to us in his latest September 19 letter: It is best to proceed in this
    field methodically.

    I can indicate some online sources of information that may assist in
    understanding the goals and methods of the experiment. A relatively
    complete set of links is available at

    >>The initial experiment of Maurice Allais took place in 1954. It consisted
    >>in launching a pendulum every 14 minutes, then to follow its evolution
    >>thereafter. An eclipse occurred during the 30 days that the experiments
    >>lasted. The pendulum then made a jump of 13,5 degrees before returning in
    >>its normal state at the end of the eclipse, two hours and half later. The
    >>researcher obtained a comparable result in the 1959 eclipse.
    >> One suspects that a gravitational effect is in question, but
    >>two measurements taken by a gravimeter in Scotland (1954), then in Italy
    >>(1965) do not give anything. On the other hand, in 1970, an eclipse again
    >>oscillated a pendulum in Boston. The data point out those of Maurice
    >>Allais, but the gravitational theory does not manage to explain them. "
    >> The Allais Effect ", as one starts to call it, was recorded once more in
    >>Romania, in 1981, on a pendulum.
    >> On the other hand, another experiment on a pendulum carried
    >>out in Finland in 1990 does not give anything. The same team of
    >>researchers led a new experiment to Mexico City in 1991 and this time, it
    >>concluded: " Perhaps ". The most recent test took place in India in 1995.
    >>This time, it is a gravimeter which recorded the Allais effect. The
    >>researchers recommended to carry out a series of additional experiments at
    >>the time of eclipses in a network. The planetary effort of August 11 was
    >>coordinated by Marshall Space Flight Center of NASA. It included a group
    >>of pendulums and gravimeters located in seven countries, all along the
    >>zone affected by the eclipse.
