Spectacular the sun rising from behind the bell tower this Monday at dawn seen from Gavà beach. Absolute beauty in this postcard of the first bars of the day, which we can relive in Las Fotos de los Lectores de La Vanguardia.
The image shows the deformation of the sun. And it is that the rays suffer a deviation when crossing the terrestrial 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".
The intense reddish sun is due to the flash of dawn, a meteorological phenomenon in which the clouds in the sky show a wide palette of colors that goes from pink to the most intense orange.
As part of the phenomenon of scattering of sunlight, in the morning and afternoon hours, when the sun is closest to the horizon, the light that reaches Earth is soft tones between red and orange.
In a certain way, when this light passes through the clouds, it illuminates them and it could be said that it colors them with those hues.
