In these images in Las Fotos de los Lectores de La Vanguardia we can see how the double rainbow forms, appears and disappears around the sanctuary of Puig-agut, in Manlleu.
A rainbow or rainbow is an optical and meteorological phenomenon that consists of the appearance in the sky of an arc (sometimes two or more) of multicolored light.
It is caused by the decomposition of sunlight in the visible spectrum, which is produced by refraction, when the sun’s rays pass through small drops of water contained in the earth’s atmosphere.
It is an arc made up of concentric colored arcs, without a solution of continuity between them, with red towards the outside and violet towards the interior.
Less frequent is the double rainbow, like that of Puig-agut, which includes a second, more subdued arc with inverted colors, that is, red towards the interior and violet towards the exterior.
The Puig-agut sanctuary, also the protagonist of this report, was the first temple of its kind in Spain to be dedicated to the Sacred Heart.
Its construction was promoted at the end of the 19th century by Ramón Madirolas y Codina, an innovative farmer who promoted it from the magazine Faro de Puig-agut.
The construction was directed by the architect August Font y Carreras, who used a neo-Gothic style with some Romanesque and even neoclassical facets, inspired by the French basilica of Tarbes.
In the photographs you can see how this landscape is ideal for walking, walking the dog or practicing physical exercise in the open air, such as running.
The snapshots have been captured at the end of the day. At this moment the anticrepuscular rays also stand out. They are nearly parallel, but appear to converge at the antisolar point, due to linear perspective. They are most often visible at sunrise or sunset.
Crepuscular rays are generally much brighter than anticrepuscular rays. This is because crepuscular rays, seen on the same side of the sky as the sun, are scattered by atmospheric light and made visible as small angles.
