At dawn on Sunday (20) to Monday (21), people will be able to see the total eclipse of the Moon throughout Brazil.
The next total eclipse will only be visible in Brazil in 2022. At this point, the moon will be a little less bright, but the difference will not be noticeable to the naked eye. naked (this is what is called the Penumbra Eclipse). The beginning of the partial eclipse will take place at 1:34 am, at which time the moon will begin to get a dark point and become darker and darker.
The beginning of the total eclipse will take place at 2:41: the Moon will take a reddish color (the so-called Blood Moon) during the whole phase of the total eclipse. The duration of the eclipse will be 1:02, that is to say until 3:43, we can still see the red moon. From that moment, the Moon will be brighter and brighter until the end of the partial eclipse that will take place at 04:51. The penumbral eclipse will end at 05:48. The same day, at 18 hours (Brasilia time), the Moon will be at its closest point to Earth, the perigee. Therefore, the Full Moon at night, from 8 pm to 9 pm, when the total lunar eclipse will occur, will be significantly brighter and endowed with a larger apparent disc, called "Super Moon" .
Josina Nascimento, a researcher at the National Observatory, explains who is a lunar eclipse: "It's when the Moon pbades through the shadow of the Earth." The eclipse will be complete if the Moon is completely submerged in the shadow, it will be partial if the moon is partially in the shade and will be dim if the moon pbades only in the twilight. "
To know the moments of eclipse for the places that are not in the twilight. Time zone of Brasilia, just take into account the time zone. With summer time, the Brasilia spindle becomes -2. For those who are in the spindle -3 hours, just subtract an hour, for those who are in the spindle of -4, just subtract 2 hours and for those who are in the spindle of -5, only 3 hours .
In the Great Victory, there are several legal points to follow the eclipse and the formation of & # 39; Superlua & # 39 ;.

What's an eclipse?
An eclipse occurs each time a body goes into the shadow of another. Each great body, that is to say, which is not a point, produces two regions of shadow: shadow and half-light. The shadow is the region of the shadow that receives no light from any point of the light source and the dim light is the region of the shade that receives light from the light source .
What is the Moon of Blood? 19659003] This is what is called the reddish-orange effect that the Moon badumes during the total eclipse. In the whole phase, when the entire moon is immersed in the shadow, we see the moon without receiving direct light from the sun, but a sunlight reaches the surface of the moon through the atmosphere of the moon. the Earth and some frequency bands of sunlight are filtered. , as happens at dusk in the morning and evening, we are used to seeing it before and after sunset.
About Eclipse
This eclipse will be the longest of the 21st century. Its totality will last 1 hour and 43 minutes. However, when the moon will appear on the Brazilian eastern horizon in the late afternoon, it will already be overshadowed. Only the last half of the eclipse can be observed from our country. But this is not a cause for discouragement: depending on the locality, it will still be possible to observe the Moon slowly emerge from the shadow of the Earth for about an hour.
The Réciféen will be the first to see the eclipse. There, the Moon will appear in the sky at 17:15. Several other cities in the Northeast, Midwest, Southeast and South will also be able to follow the total phase of the eclipse, which ends at 18:13.
If the expectations of astronomers are confirmed, it will be a major eclipse. 13 minutes after 18 hours, the Moon will come out of the darkest shadow, when the partial eclipse will start until 19:19. The top of the phenomenon occurs when the Moon enters the phase called penumbra, result of the entry of the Moon in the shadow more clearly.
At places where the moon is born after 18:13, it will be possible to observe only the partial phase when the moon leaves the darkest region of the Earth's shadow. The partial phase ends at 19:19. After this period, it is always possible to follow the penumbra phase, which takes place until 20:28. However, the penumbra phase is very subtle and almost imperceptible to the naked eye. To observe the eclipse, look for a place where the horizon is not crimped. It is not necessary to take precautions with vision. Binoculars, glbades and other instruments can be used to appreciate the phenomenon.
Lunar eclipses occur when the Moon pbades through the shadow region that the Earth projects into space. These are relatively frequent events, occurring at least twice a year somewhere on Earth. The last visible total lunar eclipse of Brazil took place on September 27, 2015 and the next one will take place on January 21, 2019.
Lunar eclipses develop in three main phases: half-light, partial and total. The penumbra phase is the first and is almost imperceptible to the naked eye. In this phase, the Moon pbades through the outermost region of the Earth's shadow cone, the dim light, where darkness is not total.
When the Moon begins to penetrate the most central region of the Earth's shadow, called Shadow, it begins. the partial phase. During this phase, it is possible to follow the shadow of the earth slowly filling the lunar disk.
During the total eclipse, the moon acquires a reddish color, caused by the refraction of sunlight by the Earth's atmosphere. In recent years, the term "Blood Moon" has been commonly used to describe this reddish appearance of the moon as a whole, but this term is not common among astronomers.
After the end of the total phase, we have the phase again. partial and finally the penumbra. The complete duration of this eclipse, including all phases, will be 6 hours and 13 minutes.
