Last July, covering the longest total lunar eclipse of the century, we conclude the text with a warning:
If this time the eastern part of Brazil is privileged, the researcher rebadures the residents on the side west of the country, declaring that in the night of 20 to 21 January 2019, "all Brazil will see the total eclipse of the moon from end to end".
For this day has come. From night (at dawn) this Sunday (20) to Monday (21), a total lunar eclipse occurs and will be visible from all over Brazil.
The satellite will be in the "shadow" of our planet and will acquire a red color. Sunlight is not blocked when it pbades through the earth's atmosphere. However, it is spilled and absorbed, as in a "filtering" that gives an orange or reddish hue. Therefore, the phenomenon was called the "blood moon". As the Moon will also be close to its perigee, the closest point to Earth, it is also called the "blood superferment".
According to EarthSky the event will be visible to all.
According to the blog of the astronomer Cássio Barbosa in G1 the event should begin at 0:36 from Sunday evening to Monday, at the time of Brasilia when the moon will enter the so-called penumbra, the most diffuse part of the shadow cast by the Earth. It begins to go into the shadow, the most central and darkest part of the shadow, at 1:33.
No special equipment is needed to observe the lunar eclipse, but binoculars or telescopes help you visualize it better. Being in a wide place also helps.
This is the only total eclipse of the year – in July, there will be partial and restricted visibility to certain areas of Brazil. After that, we will have another total eclipse in 2021, which will no longer be visible from Brazil. It is only in 2022 that we will be able to witness another phenomenon of the type of our country. It is better to enjoy it.
