Eclipse Anular (En Construcción )

Allais’ effect Gravity. Analizing  local gravity perturbations into a total eclipse have been of interest since 50’s of last century. Have to think  gravity are propagated by gravitational waves , we should expect some changes in the gravity local components because Sun does not play a fundamental role. (So the asking is : Moon is transparent to gravitational waves?)

The local gravity changing test was made by a french man, Maurice Allais, in 1954. Studying the variations at a Foucault´s pendulum, he determined a “gap” and peculiar movements during a total solar eclipse, so this phenomena is called “Allais´ effect”

The strange and pictoresque of this fact is M. Allais, in addition to being a great physicist, he work into Economy theory and he won Nobel prize in Economy in 1988, too.

Half-moon shaped shadowsa Other curious effect during an eclipse are the projecting shadows. Light passing through the little spaces between the leaves, provokes half-moon shaped shadows on the ground, under the trees, for instance. This shadows are available  using  pinholes of the venetian blinds, bevelled-cristal windows, prism-shaped corners too, because   light refraction  projects half-moon rainbow-coloured features on unexpected places.

Similar shaped shadows appears at annularity, but in this case the outer ring produces the shadows, so some kind of fire rings are produced.

Refracción de la Atmósfera lunarRefraction on the Moon´s atmospherer  These eclipses have relative importance because they produce less relevant effects compared to total ones and the are visible in big  world sectors. Sometimes there are sunspots  and Moon are occulting them, sunspots distortion can be gazed through the Moon faint atmosphere.
