The citizens of Brasilia have an appointment with the sky this Sunday (5/15), starting at 22:30 pm when there is a full lunar eclipse known as the “blood moon”. The name is given to the fact that the satellite is red in color, which will allow only the red ray of the color spectrum to pass through as a result of blocking the Earth’s sunlight. The peak of the phenomenon, which can be seen with the naked eye, will be around 1 am.

Once the light reaches the celestial body, it reflects the Moon and can be seen from Earth. Astronomer Adriano Leonês, a 35-year-old astronomer, explains that on average, two eclipses occur every six months — one sun and one moon — between them for a few days. “The next moons will be on November 8 and May 5, 2023. None of them will be seen from Brazil,” he says.

Enthusiastic about astronomy since he was a child, 23-year-old Leonardo Pereira has always liked to follow phenomena like this weekend. Looking forward to this Sunday (15/5) he hopes to pick up some of the beauty of the sky. Despite the fear that the clouds will cover the natural satellite, the Santa Maria resident stressed that he will not make the effort to enjoy the event. “The moon reminds me that there are so many beauties out there that we barely realize,” says the pedagogue.

Mateus Felix’s 28-year history began very early with astronomy, ranging in age from 6 to 8 years. His interest arose in his passion and desire to understand the universe in some way. “Ever since I was a child, I’ve always been fascinated by trying to understand the role we play in the world. developer.

Mateus is currently the president of the Brazilian Astronomy Club (Casb) and joined when he was 12 years old. Grateful to those who helped him along the way, he says it’s not easy to spark people’s passion for the sky and the stars. The last time the programmer saw an eclipse was in 2015; so they are eager for Sunday (15/5). “This is one of the most attention-grabbing astronomical phenomena. Better than that, only solar eclipses. And the next chance to see a full lunar eclipse in Brazil will only be in 2025,” said a Southwestern neighbor.

Weather forecast

Members of the Casb will be in Praça dos Três Poderes to follow the celestial ceremony, making the telescopes available to the public. However, in the case of cloudless skies, the eclipse will be open from any location. On Sunday (15/5), despite the dry air mass in the federal capital, the clouds should change, but the chances of rain are low. “I think there will be no vision problems,” commented Heráclio Alves of the National Meteorological Institute (Inmet).

From next Monday, however, DF is expected to enter a more intense period of precipitation. The average weekend temperature will be between 14 ° C and 30 ° C. In the morning, the relative humidity will remain at 95%, with the possibility of reaching 30% in the afternoon.


An eclipse occurs when one celestial object passes through the shadow of another. The names are based on the celestial body where the view was locked

lunar eclipse
• It occurs when the moon passes through the shadow of the Earth. The phenomenon occurs only during the entire phase, when the planet is located between the satellite and the Sun. A full eclipse — known as the blood moon — can last up to two hours.

solar eclipse
• Occurs when the Moon is between the Earth and the Sun, blocking some of the light it emits. Since the satellite must be between the planet and the stars, this event only occurs during the new lunar phase. In this case, there is no significant change in brightness during the day.

eclipse canceled
• When the moon is close to the farthest point in its orbit, or when it appears too small to fully cover the sun, a bright ring of sunlight is created around the satellite. The phenomenon covers almost the entire visible part of the Sun.
