At dawn of 20 at 21 (Sunday to Monday) all Brazil will be able to follow the total eclipse of the Moon, which will make the phenomenon even more attractive: that day, there will be the SuperLua – when the satellite will be near the Earth.

From 0h37 (e) At that moment, the Moon will be a little less brilliant, but the difference will not be noticeable to the naked eye: it is the so-called eclipse of Pénumbre.

The beginning of the total eclipse will take place at 2:41: the Moon takes on a reddish color (the so-called Blood Moon). ) during the entire phase of the total eclipse. The duration of the eclipse will be 1:02 – until 3:43, we can still see the red moon. From this moment, the Moon will illuminate more and more until the end of the partial eclipse, which will take place at 4:51. The penumbral eclipse will end at 17:48.

The same day, at 18 hours (Brasilia time), the Moon will be at its closest point to Earth, the perigee. Therefore, the Full Moon of the night from the 20th to the 21st will be significantly brighter and with a larger apparent disc, the Superlua.

Researcher Josina Nascimento, Coordinator of Astronomy and Astrophysics at the National Observatory, explains that the lunar eclipse "This is when the Moon pbades through the Earth's shadow 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 shadow and will be dimmed if the moon pbades only in the penumbra. "

To know the moments of eclipse for places that are not in the penumbra time zone of Brasilia, just take into account the time zone. At daylight saving time, the Brasilia time zone becomes -2. For those who are in the time zone -3 hours, just subtract an hour, for those who are in the time zone of -4, just subtract 2 hours and for those who are in the time zone of -5, just subtract 3 hours.

After that, the next total lunar eclipse visible in Brazil will take place in 2022.

What's an eclipse?

An eclipse occurs whenever 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 shade 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 blood moon?

This 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 light from the sun reaches the moon's surface through the atmosphere of the moon. Earth and some frequency bands of sunlight are filtered. just as it happens at morning and evening twilights that we are used to seeing before and after sunset.
