Spectacular first sunrise of March from Gavà beach, in Baix Llobregat, as can be seen in this snapshot in The Photos of the Readers of La Vanguardia.
We can observe the two ships caught between the impressive crepuscular rays, announcing the important change of time that we will soon have.
The phenomenon of crepuscular rays also 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".
