by Set the clock to wake up because we will have an eclipse of Mars this morning. And the phenomenon can be seen in some areas here in Brazil!
The eclipse will take place in the early hours of Monday to Tuesday (31) around 1am Brasilia time.
Anyone west of the Amazon and Roraima will be able to witness the total lunar eclipse of Mars. It is good to hope that the sky is clear at that time.
“It will be an occultation during which the planet will pass very close to the Moon’s south pole. It will disappear and reappear just 18 minutes later. In short, the times really change, depending on the location of the observer, not only because of the time zone conversion, but mainly because of the position of the stars in the sky from the observer’s point of view,” explained Marcelo Zurita, member. of the Brazilian Astronomical Society (SAB) and technical director of the Brazilian Meteor Observation Network (BRAMON).
How will the phenomenon
For the Moon to pass “in front” of the Red Planet, from Earth’s point of view, the two stars obviously have to be close to each other.
This closeness, known as an astronomical conjunction, will occur around 1:20 AM Brasilia Time – 0:20 AM. Amazon time.
Municipalities where it will be visible
Only one Brazilian municipality will be able to reflect on the phenomenon in its entirety. In Ipixuna (AM), it will be possible to see the disappearance of Mars at 01:06 AM. and the reappearance at 01:24 am. (local time).
In other Amazon cities such as Lábrea, São Gabriel da Cachoeira and Tabatinga, in addition to Boa Vista, in Roraima, observers may only be able to see the planet disappear.
disapprove
Along with the conjunction between the Moon and Mars, an appulse occurs, a term that refers to the minimum apparent separation between two bodies in the sky, according to the Starwalk Space astronomy guide.
What differentiates the two expressions is that, although the term “conjunction” is also widely used to represent an apparent approach between two bodies, technically, astronomical conjunction occurs only when the two objects share the same right elevation (equivalent to astronomical coordinates in the longitude of the Earth).
the position of the moon
Lunar occultations are only visible from a small fraction of Earth’s surface.
As the Moon is much closer to our planet than other celestial objects, its position in the sky differs depending on the exact position of the observer on Earth due to its large parallax (difference in the apparent position of an object relative to the background, as seen by observers at different locations or by a moving observer).
The position of the Moon as seen from two points on opposite sides of the Earth can vary by up to two degrees, or four times the diameter of the full moon.
This means that if the Moon is aligned to pass in front of a particular object to an observer on one side of the Earth, it will appear up to two degrees away from that object on the other side of the globe.
