At lunchtime I recorded this interval video from the balcony of my house, in the village of Altet, in the Urgell region. We can see in The Photos of the Readers of La Vanguardia an hour and forty minutes summarized in 20 seconds.
You can see in the images the spectacular advance and formation of the sea of clouds, which are forming in the sky and which we see appear and disappear.
Later, on a walk along the west side of the surroundings of Altet, I was able to capture this other series of photographs of the sunset, where we can contemplate the crepuscular rays showing themselves over the landscape.
This phenomenon receives other names, such as Jacob's ladder or God's fingers, and it also occurs at sunset. Crepuscular rays, in atmospheric optics, are rays of sunlight that appear to radiate from a single point in the sky.
These rays flow through openings in clouds (mostly stratocumulus) or between other objects. They are columns of sunlit air separated by dark cloud shadow regions.
The name comes from its frequent appearances during the twilight hours (sunrise and sunset), when the contrasts between light and dark are most obvious. It is not for nothing that crepuscular comes from the Latin word crepusculum which means "twilight".
