People who decide to wake up early-or dawn-next Friday (14/3) can follow a true heavenly delight.
It is that this day will happen a total eclipse of the moon – and it will be possible to observe all phases of this phenomenon in Brazil.
Our natural satellite will also gain reddish tones, which inspires the name “Blood Moon” (Understand the following reasons).
But how to follow the eclipse? And will weather conditions help observers? Check out the answers to these and other questions below.

When does the total moon eclipse happen?
The National Observatory explains that the whole of Brazil will be able to observe all phases of the total eclipse during the early hours of March 14, next Friday.
Check out the moment when all the stages of the phenomenon will happen, in Brasilia time:
- Beginning of the penumbral eclipse: 00:57
- Beginning of the partial eclipse: 02:10
- Start of Total Eclipse: 03:26
- Maximum of the total eclipse: 03:59
- Fim do Eclipse Total: 04:31
- End of partial eclipse: 05:48
- Fim do Eclipse Penumbral: 07:00
The exceptions are the South, especially Santa Catarina and Rio Grande do Sul, the north of Minas Gerais and Espírito Santo and much of the Northeast where the forecast is open time.
However, as the phenomenon will happen for many hours-practically throughout the morning and early Friday morning-the tendency is that it is visible at some point in the morning/morning across the country.
What is a lunar eclipse?
As mentioned earlier, this process is divided into stages: the penumbral, partial and total phases.
The phenomenon begins when the moon enters the shadow (or dim light) of the earth.
The total eclipse occurs when the moon is completely covered in the shadow of the earth (called the “umbra”).
“Every total eclipse goes through the penumbral and partial phases before and after the total phase,” explained Nascimento.
“After the total eclipse, there is a new partial eclipse and new penumbral eclipse, because the moon will be leaving the shadow of the earth,” added the astronomer.
What is the blood moon?
The “Blood Moon” refers to the way the satellite gains a deep and accurate red tone during the eclipse.
This happens thanks to a process known as “Rayleigh’s dispersion,” which also makes the sky blue and orange or red sunset.
In short, it “spreads” the lights with larger wave lengths, such as blue, and allows the smaller wavelength lights, such as red, to invite to the umbra where it remains visible.
During the lunar eclipse, all the light that shines on the moon passes through the atmosphere of the earth.
In practice, it is as if the sunset are designed on the lunar surface.
“The reddish aspect of the moon during the total eclipse is due to the way sunlight interacts with the earthly atmosphere. Even totally covered by the dark shadow of the earth, the moon still receives sunlight indirectly, filtered by the atmosphere, ”summarizes the National Observatory.

How to see the lunar eclipse?
To get the best vision of the eclipse, the ideal is to go to a dark place, preferably without buildings, tall trees or surrounding lights.
The phenomenon will be visible to the naked eye, without the need for special instruments.
If you want to take pictures of the moon, the ideal is to put the camera on a tripod and configure it for a longer exhibition. Thus, it will be possible to capture all the details of our natural satellite.
The National Observatory also points out that, unlike solar eclipse, the lunar eclipse does not require eye care and can be observed for the time the person wants.
“The moon will be very high in the sky at the beginning of the penumbral eclipse and will be west throughout the eclipse,” says the institution.
“The west side is the side where the sun sets. So we recommend that people position themselves in places that have seen unimpeded to the west, ”concludes the observatory.
The next total lunar Eclipe that will be visible in the Americas should only happen on March 3, 2026, according to NASA.
