In the Photos of the Readers of La Vanguardia we can see a colorful arc of fog that occurred when it was already dispersing in Vic, Osona region.
The arc of fog occurs when we have the low sun early in the day behind us. The meteorological phenomenon merges with the optical effect. It is as if a bridge forms before us.
We can see the effect of the fog arc clearly in an image with my shadow cast on the ground, elongated due to the sun with low altitude.
As you can see in the images, the niela arch is like the rainbow, but almost white in color, without the multicolored nuances of the rainbow.
One of the elements that stands out in these snapshots is that the arc of fog has formed above the road, covering it from side to side. We can even see a car passing below.
