Today at dawn on the beach of Gavà, in the Baix Llobregat, it was possible to see a spectacular Etruscan vase as defined by the novelist Julio Verne as the Omega effect.
The so-called Omega effect is formed when the air, in contact with the surface, which is very dense and at the same time warmer, produces the refraction of light, which deforms the sun and creates the mirror effect.
When observing this optical illusion it appears that the base of the sun rests its “foot” on the horizon line that separates the sea from the sky.
Optical effects caused by Earth’s atmosphere can cause distant objects near the horizon, including the Sun and Moon, to take on shapes that not only pique our attention or surprise us, but invite us to imagine.
There was even an audience admiring her beauty. Radiant dawn, without a doubt, with another image that has been left to us for The Photos of the Readers of La Vanguardia in which we see a walker in the sea, within the beam of the pillar of reflected sunlight, and the plane as a witness above the sun.
A pillar light is an atmospheric optical phenomenon in which a vertical beam of light appears to extend above and/or below a light source. The effect is created by the reflection of light from small ice crystals that are suspended in the atmosphere or that comprise high-altitude clouds (for example, cirrostratus or cirrus clouds).
If the light comes from the sun (usually when it is near or even below the horizon), the phenomenon is called a solar pillar, as in this case in Gavà.
