The 2024 total solar eclipse is coming. Anyone interested will be in North America. We cannot forget about the people, who live or will temporarily stay in Western Europe on the day when the...
This text shows some guidelines for the brief moment of the total solar eclipse 2024 occurrence at twilight, which presumably will allow for a fantastic view of the 12P/Pons-Brooks comet being close to its...
This article is about the general definition of the realm, which has been described occasionally on this website since 2017. Therefore I guess I should have done it much earlier, however better late than...

It’s still quite a lot of time to the 2026 total solar eclipse event, which has been already considered by me in terms of the possibility of seeing its impact on the atmosphere when...
The total solar eclipse on December 14, 2020, was the last one in the 2nd decade and obviously the first “Twenty Years Solar Eclipse Path Tables” of the XXI century. Most people call this...
My third remote observation of the solar eclipse was aimed at the fleeting lunar shadow when the Sun was already below the horizon. Previously I hadn’t had occasion to see a similar effect, as...
This article presents the result of the longest distance observation in my life. Because it was an effect of the light phenomenon, not widely discussed by myself so far I decided to develop this topic, because of its influence on the far realing views during some specified conditions (tick haze trapped in low-level of the […]
The contrast issue has been mentioned in this article, and either during the description of the role of horizontal visibility in long-distance observations. Because the information is not sufficient enough for my further studies...

A vast majority of people around the World don’t realize something like starlight. Nowadays, when skies are highly polluted with light, most people cannot even see the Milky Way in the sky. It’s known...

A solar eclipse is the most spectacular natural phenomenon, as we can see on Earth. It induces at least a dozen or so other events, which occurrence can be observed during this time. In...
The area covered by umbra is the most spectacular of the whole solar eclipse phenomenon, therefore I would like to pay particular attention to this. Because I was watching the totality only once, I...
Recently I have shown the light level changes during the solar eclipse. The illumination level is strongly related to the sky brightness. Both of them change at the same time throughout the eclipse. In...
The illuminance level and sky brightness are very important elements of solar eclipse phenomena because both are clearly noticeable by the observer along with his eye adaptation. When the eclipse phase is deep and...

A solar eclipse is a magnificent natural phenomenon, during which the direct Sun is shadowed by the moon to darken the daytime sky (Vollmer, Shaw, 2018). In this article, I would like to draw...
The light scattering issue in the Earth’s atmosphere has been described recently for typical daylight, evening, and twilight conditions. In this article, I would like to explain a light scattering phenomenon under total solar...
Light is omnipresent in the Universe and the environment. This is electromagnetic radiation, that can be detected by the human eye. I have written more about the light and the ways of measurement in this...
Light surrounds us everywhere. This is an electromagnetic wave, which is the fastest in the environment. For Earth, the main source of light is the Sun. Another source is artificial lightning, created by humankind....
Previously I have described the light scattering mechanism on the smallest particles of the Earth’s atmosphere, where mainly the Rayleigh Scattering plays a role. Now is the time to round off this whole article...
When we ask ourselves why the sky is blue we can think about the most important type of light scattering in the Earth’s atmosphere. This is Rayleigh scattering. I was writing about this type...
1. INTRODUCTION My deep interest in the light scattering in Earth’s atmosphere arose out of my observations of the behavior of the Earth’s atmosphere, especially around sunrise, sunset (golden hour, blue hour, twilight), and...
