Just before or after sunset, we notice a thick stream of sunlight emerging vertically from the Sun. This vertical column of light is referred to as sun pillar and is due to the presence of light-reflecting snowflakes or ice particles in the atmosphere.
What are Crepuscular Rays?
However, it is not just the clouds that can create this visually beautiful effect. As aforementioned, when the Sun hides behind the mountains, you can see the crepuscular rays.
You can view this effect right in your house if you have tall ceilings and sufficient amount of haze particles. When sunlight enters indoors, you can notice beams of light emerging through the window.
When Do They Occur?
Crepuscular rays are also sometimes referred to as God rays, as the radiating rays give a feeling of divine power just behind the cloud. Nevertheless it is a stunning display of light beams that appear to be emerging from a single point.
As the Sun starts setting in the horizon, we notice crepuscular rays radiating into the sky. Sometimes, these crepuscular rays are seen meeting at a singular point on the opposite side of the horizon.
These are known as anticrepuscular rays and are a spectacular sight to behold. However, these rays are not easily visible as they are much fainter than crepuscular rays. Also, to catch a glimpse of this phenomenon, right conditions need to exist. Too much dust particles in the atmosphere considerably reduces the chances of viewing anticrepuscular rays.
So the next time you see the Sun setting in the west and view the crepuscular rays, don't forget to view the east side of the horizon. I am sure you will see anticrepuscular ways converging on the opposite side.
