An original point of view
We are over a month ahead of the last partial solar eclipse on Saturday, March 29, 2025. It wasn’t a big eclipse in most European countries. Because of the largest magnitude of 0.9376, this eclipse was classified as a deep partial. Considering the Gamma factor 1.0405, the totality was visible about 210 km above the … Read more
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 event occurs. Therefore I decided to prepare the text, which presents the guideline for this specific kind of observation. The guideline … Read more
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 perihelion point. 1. 12P/PONS – BROOKS COMET – GENERAL INFORMATION 12P/Pons-Brooks is a periodic, Halley-type comet, … Read more
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 never. Anyhow today I would like to focus exactly on both the primary definition as well as the basic divisions of … Read more
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 phenomenon happens below the horizon. However, the character of this path of totality requires attention far earlier than normal, as … Read more
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 eclipse the COVID eclipse, due to omnipresent travel restrictions, which kept a lot of eclipse chasers in their homes. They could … Read more
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 I watched the partial phases only. This observation was spectacular, because of the circumstances. I know only a few publications presenting … Read more
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 I would like to point out more matters arising out of the contrast in a general sense. These elements are very … Read more
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 history, that during a huge power cut in Los Angeles in 1994 people were calling authorities, asking them what is this … Read more
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 this article, I would like to list 10 of the most intriguing and uncommon phenomena, which an observer is able to … Read more
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 am going to use some supporting materials next to my own pictures. How the lunar shadow looks? We can consider it … Read more
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 this article I would like to focus on these changes, having external data from Wolfgang Strickling. Because his observation venue was … Read more
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 turning into totality, the light level changes drastically, much quicker than on any other occasion. It makes the solar eclipse one … Read more
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 your attention to another phenomenon, which I “discovered” accidentally during the Great American Eclipse – the visual range changes. 1. INTRODUCTION … Read more
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 eclipse conditions, which was observed accidentally during the 2017 Great American Eclipse. Initially, the aim of my observation was a record … Read more
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 article. Now I would like to describe a very common process, occurring both in the Universe and in Earth’s atmosphere, which … Read more
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. In this article, I would like to bring a piece of relevant information about the essence of light surrounding us and … Read more
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 and say something more about a different group of elements, that also contributes to the light scattering process. There are bigger … Read more
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 of light scattering on some occasions, like watching the solar eclipse through the webcams or wondering about the Martian sky. Today … Read more
