  The failure of the laser-interferometer gravitational wave antennas to
measure the tiny changes of lengths many orders of magnitude smaller than the
diameter of a proton raises the question of whether the reason for this failure
is a large gravitational wave background noise, and if so, where this
background noise is coming from. It is conjectured that it comes from
gravitational waves emitted from a magnetohydrodynamic dynamo in the center of
the sun, with the large magnetic field from this dynamo shielded by
thermomagnetic currents in the tachocline. Using the moon as a large Weber bar,
these gravitational waves could possibly be detected by the Poisson diffraction
into the center of the lunar shadow during a total solar eclipse.
