From ancient times, lunar and solar eclipses were considered a sign from above. Some peoples were afraid of such a phenomenon and expected the end of the world, while others were confident that something positive would happen soon. What is a solar eclipse, astrologers began to study a long time ago. It was found that this is the most common natural phenomenon that occurs not so rarely.

What is it?

What is a solar eclipse, today every elementary school student knows. The earth moves around the sun, and the moon moves around our planet. Full or partial overlapping of the solar disk by the moon is called an eclipse. Earth, Moon and Sun become in one line. It is worth noting that an eclipse can only occur on a new moon. That is, when the Moon cannot be seen at all from the Earth.

A total eclipse is not always visible. The overlap of the solar disk depends on which orbit the Earth's satellite moves in a certain period of time. Most often you can see a partial eclipse. People who are busy with their own affairs anddo not pay attention to the sun, they may miss a natural phenomenon altogether. Visually, a partial eclipse is similar to twilight. During the day it can get a little darker outside. It may look like it's going to rain soon.

Astrologers have long been able to calculate how many solar eclipses occur on average per year. This phenomenon is not so rare and is repeated 5-6 times. Most often, the sun is covered by the moon by no more than 70%. At the same time, it is not possible to observe a natural phenomenon from all points of the globe. In addition, the eclipse may not last very long. Full overlap of the solar disk can last no more than 10 minutes.

What is a lunar eclipse?

A beautiful natural phenomenon can be observed not only in the daytime. At night, everyone can see a lunar eclipse from time to time. It represents the overlap of the lunar disk with the shadow of the Earth. Most often, a total eclipse can be observed in that part of the planet where the Moon at the time of the natural phenomenon is above the horizon. During an eclipse, the Earth's satellite does not disappear completely. Observers can see the outline of the moon colored bright orange. This is due to the fact that even at the time of the eclipse, the Moon continues to beat off the sun's rays with even greater intensity.

Lunar eclipses occur much less frequently than solar eclipses. You can observe this phenomenon no more than twice a year. A complete overlap of the earth's satellite disk is quite rare. Lunar eclipse people do not attach great importance. Most often, this natural phenomenon remainswithout attention. In fact, everything that happens in nature affects human he alth and behavior. Therefore, it is better for hypersensitive people to prepare in advance for such a phenomenon as a lunar eclipse.

Types of lunar and solar eclipses

The same eclipses are quite rare. Depending on which part of the celestial body is covered by a shadow, there are partial and total eclipses. With a total solar eclipse, twilight occurs only at a certain point on the globe. At this time, happy observers can only see the outlines of the solar disk. This phenomenon is considered quite rare and unique. An incomplete solar eclipse occurs much more often when the moon covers only a small part of the solar disk. Such a natural phenomenon can no longer be called unique. It is worth noting that the same eclipse can be total and partial for observers from different parts of the planet.

Lunar eclipses are also total and partial. If the satellite is completely in the shadow of the Earth, it is not lost from the field of view. The outlines of the moon can still be seen. At the same time, the night sky body acquires a bright shade. The sun's rays continue to illuminate the moon. A partial eclipse is an overlap of the celestial body on only one side. This phenomenon is very similar to the new moon. In most cases, people are not even aware that an eclipse is happening in the night sky.

The impact of a solar eclipse on a person

Any natural phenomena affect the general conditionhuman body. Hypersensitive people are especially affected. They can feel the deterioration of well-being a few days before the eclipse. Older people may feel a headache, general weakness, and chronic diseases are exacerbated. Many have to limit their activity and take more care of their he alth. Hypersensitive people should clarify in advance when the next solar eclipse will be. On the day of the celestial phenomenon, it is generally advisable to stay at home. It is not recommended to go outside also for completely he althy people.

Pregnant women are sensitive not only to solar but also to lunar eclipses. Doctors advise not to be under the open rays of the heavenly body during a natural phenomenon. This is fraught not only with poor he alth, but also with pathologies of fetal development. When two luminaries are at the same point, their energy has a strong impact on a person. At best, a young woman in position will feel a severe headache, and at worst, premature birth may begin. Meanwhile, people have noticed since ancient times that children born at the time of a solar or lunar eclipse have good he alth and achieve success in life.

The influence of a solar eclipse on a person is also considered by psychologists. It is believed that during such natural phenomena, the mind and emotional sphere of people are too vulnerable. During eclipses, difficult tasks should not be solved. And people who suffer from mental disorders should notleave unattended. It is during lunar or solar eclipses that suicides most often occur.

How to observe a solar eclipse?

A unique natural phenomenon, although it has a negative impact on human he alth, cannot be ignored. Solar eclipse is really very beautiful. But in order to observe him without harm to he alth, you must follow some rules. In no case should you look at the heavenly body without protective devices. Many do not know how to observe a solar eclipse correctly and use a telescope or binoculars for this purpose. With the help of these devices, you can only see the celestial body at a closer distance. But first of all, you need to take care of eye safety.

You can not look at the eclipse also through sunglasses or smoked glass. These things do not fully protect against direct rays. With a long examination of the celestial body, you can get a retinal burn. How to observe a solar eclipse correctly? In order to see a unique celestial phenomenon without harm to he alth, it is necessary to use special solar filters. You can buy them in specialized stores of photo and video equipment. Without a protective device, only a complete overlap of the heavenly body can be observed. The effect of a solar eclipse on the eyes at this moment is minimal. But to determine visually whether there is a complete overlap of the solar disk or only a partial one, only a true professional can.

Usesolar filters can be used alone or together with binoculars. The second option is more preferable for those who want to see all the details of the eclipse. Those who want to capture the moment in a photo or video should also not forget about filters.

The impact of eclipses on nature

Few people know that celestial phenomena affect not only human he alth, but also nature. A few weeks or days before the eclipse, the weather can change dramatically. Frosts often begin in warm May, and warm days suddenly come in winter. But such changes in nature are absolutely harmless. But the eclipse can provoke more dangerous changes in nature. These include tsunamis and hurricanes. It has long been noted that during lunar and solar eclipses, the activity of the World Ocean increases several times. When the next solar eclipse will be, every captain of the ship should know. This is the only way to avoid tragedy. Long trips by sea are not recommended for planning on the day when a natural phenomenon should occur.

The most dangerous changes in nature occur where a total lunar or solar eclipse can be observed. Scientists around the world are studying an unusual natural phenomenon. Already today we managed to find out what a solar eclipse is and when it will happen next. The schedule of celestial phenomena is scheduled for decades ahead. Thanks to the hard work of astrologers, many natural disasters can be avoided and protected from tsunamis, earthquakes and hurricanes.

1999 Solar Eclipse

One of the brightest solar eclipses occurred on August 11, 1999. Almost all inhabitants of Europe could observe the complete overlap of the disk of the celestial body. The most fortunate observers in Bucharest. Such a natural phenomenon in the XX century could be seen for the first time. The total eclipse did not last long. People could observe the unique phenomenon for no more than three minutes.

The solar eclipse in Moscow was only partially visible to observers. The solar disk was covered only by 70%. Despite this, there were many who wanted to see the unique celestial phenomenon. And it is no coincidence. After all, the national TV channels began to talk about the fact that a solar eclipse would happen a few weeks in advance. Entrepreneurs were also not far behind. Special disposable glasses appeared on sale, with which you could look at the sun without harm to your eyesight.

The solar eclipse had a limited time. However, everyone was able to see how the moon covers the solar disk. This performance was truly unique. Some artists even described the natural phenomenon in their works. For example, Elena Voynarovskaya wrote a whole poem, which was called "Sun, do not disappear." The eclipse is also described in the first part of the famous work "Day Watch".

A unique 21st century eclipse

The younger generation already knows perfectly well what a solar eclipse is. But how this phenomenon occurs, many schoolchildren have not been able to see before. The situation was corrected in March 2015. ATOn this day, a natural phenomenon occurred that will be remembered by many for a long time. On March 20, residents of the CIS countries could see the solar eclipse. Astrologers note that the most difficult period was from March 16 to April 8. The influence of a solar eclipse on a person at this time was the strongest. People with chronic diseases felt the exacerbation of ailments. But there was also a positive side. An eclipse is a time of release of a huge amount of energy. Those who used it wisely managed to make successful deals and make the right contacts.

The inhabitants of the planet could observe the total eclipse in the Arctic and in the north of the Atlantic Ocean. On the territory of Russia, the process could be best seen in the city of Murmansk. The solar eclipse in Moscow began around 13:00 in the afternoon. It was only partially visible. Many residents of the metropolis did not even pay attention to the fact that the Sun hid behind the Moon. It was possible to see the eclipse only with the help of special devices.

When will the next eclipse be visible?

Scientists have long studied the nature of various celestial phenomena. When and where will the next solar eclipse be? You can find out about it right now. During the entire 21st century, 224 solar eclipses should occur. Only 68 of them will be complete. But annular eclipses deserve much more attention. That was the solar eclipse of 1999. The next one that residents of Europe and the CIS countries will be able to watch will happen on February 26, 2017. August 21 this yearthere will be a total eclipse, the duration of which will be only 2 minutes and 40 seconds.

Things to remember?

Those who want to witness a unique natural phenomenon should prepare in advance. A solar eclipse has a limited time. Therefore, you should know in advance the exact hours of its onset. You can always hear about a total or partial eclipse in the news or find out on astrological sites. Information is released weeks in advance of the natural event.

Eclipse can affect he alth. The eyes are the first to suffer. Do not look at the sky without special protective devices. On March 20, only those who had protective filters could see the solar eclipse. You can buy them today without any problems in a specialized store.
