Trapped by the moon and the sun

Two spring phenomena come together day and night: the Pink Moon and solar deformation, as can be seen in this series of photographs in Las Fotos de los Lectores de La Vanguardia captured in Mijas.

The full moon in April is known as the Pink Moon or Pascual Moon, as it coincides with Easter. It is the first of spring, so it also marks the dates of Easter.

The reference to the "pink moon" does not refer to its color, but rather comes from Native American tradition associating it with the flowering of a North American native plant, pink moss or Phlox subulata, which blooms in shades of pink in spring.

There is also an explanation for why it looks so shiny. And it is that this full moon occurs at the closest moment between our natural satellite and planet Earth, so it appears larger and brighter.

For its part, the deformation of the sun is due to the fact that the sun's rays undergo a deviation when passing through the earth's atmosphere. This is an optical phenomenon known as "refraction" and the angle that light is bent after passing through the Earth's atmosphere is known as the "angle of refraction".

Refraction is the change in direction and speed that a wave experiences when passing from one medium to another with a different refractive index. It is also very well observed with respect to the sun when, for example, the so-called Omega effect occurs.
