In The Photos of the Readers of La Vanguardia we can see the phenomenon called “solar corona” in Vic. It is rare to see since multiple factors have to be established.
And, in this case, we can also see how a solar corona has formed in an urban environment, that of the capital of Osona.
It is an effect that is produced by the diffraction of light and the small drops or ice crystals that are in the fine clouds.
For the phenomenon of the solar corona to occur, thin clouds, of the cirrostratus or altostratus type, are necessary.
The colors of the crown are iridescent, similar to the colors drawn by soap bubbles. They have an intensely bright, almost white center, where all the coronas overlap.
