In Las Fotos de los Lectores de La Vanguardia we can see these images of the beautiful sunrise with mist and a reddish sky in Malleu, in the Osona region, on the days when the sun rises earlier, already at the gates of summer.

On June 21, the summer solstice is celebrated, which defines the beginning of the warmest months of the year, because the Sun will reach its maximum declination, projecting its light on the maximum geographical latitude of the Earth.

Fog is a meteorological phenomenon, which consists of the suspension of very small droplets of water in the atmosphere or of humid hygroscopic particles, which reduce horizontal visibility at a distance of one kilometer or more.

If the meteorological phenomenon gives a vision of 1 km or less, it is considered as fog; and if it allows you to see more than 1 km, the phenomenon is fog.

The reddish sky is due to the glare, 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.
