Sun halo and other phenomena

05 Mar 2024

We are in a very turbulent and fast-paced period of atmospheric events. Strong altitudinal currents of warm and cold, moist and dry air are present.

Due to this, various phenomena occur high in the atmosphere, water vapor particles at different heights and at different temperatures turn into various ice crystals.

We know that water and water vapor and ice cause certain “illusions” that we see with the naked eye.

Rainbow colors or the distortion of a straight stick when immersed in water are just some of the results of these events. What we can notice at this time of the year, especially in the morning and evening hours, are the appearances of the Solar halo, the fake Sun, pillars of light…

A solar halo is a phenomenon when, due to the refraction of light on ice crystals, a partial or complete circle of light with a diameter of 22.5° is visible around the Sun through a thin layer of clouds, a halo with a diameter of 44° is even rarer.

A halo often forms around the Moon and can look somewhat ominous at night, even though it is a completely natural and harmless phenomenon.

A so-called false Sun represents a phenomenon in the atmosphere that occurs in the plane of the Sun but at 22° to the left and/or right after sunrise or shortly before sunset. The phenomenon is caused by the refraction of light on hexagonal ice crystals when passing through thin clouds.

The solar pole is formed before or at the time of sunrise or sunset. It is a striking phenomenon of a vertical column of light that occurs high in the atmosphere due to the reflection of light from prismatic hexagonal ice crystals.

These are just some of the possible appearances in the sky. Sometimes these phenomena are almost imperceptible and sometimes they are really striking.

Therefore, when you go to work or school, or when you look out the window in the evening or take a walk, look at the sky. The sights you can see are truly enchanting.
