The largest lunar eclipse 21st Century The phenomenon, also known as Blood Moon, begins at 4:30 pm – the total eclipse will last about an hour and a half, according to the National Observatory. This is the last total lunar eclipse that can be observed in Brazil this year, the next in January 2019.

In the eastern part of the country, where states like Rio de Janeiro and Bahia, the Moon will be born during the total phase of the eclipse. In the west, however, Brazilians will observe the moon in its partial phase.

The National Observatory recommends that people seek a place where it is possible to see the sky near the horizon in the east.

The moon comes out of the darkest shadow – the movement marks the beginning of the partial eclipse, which continues until 19:19. Then the penumbral phase begins, when the Moon enters its lighter shadow.

For an eclipse, the Earth, the Moon and the Sun must be aligned. According to the order, the result is a solar eclipse (with the Moon between the Sun and the Earth) or lunar (Earth between the Sun and the Moon). Eclipses can be total, partial or penumbral. The total lunar eclipse occurs when the satellite penetrates completely into the shadow area projected by the Earth. Because of the red coloring that the Moon acquires during the phenomenon, it receives the informal name of "Blood Moon".

The partial occurs when only part of the moon is obscured. The penumbra occurs when the Moon pbades through the transition region between light and shadow, the Earth only intercepting part of the sun's rays.
