If the sky is clear on a Sunday evening, the Edmontonians can go outside for a luminous show of different varieties, as the general lunar eclipse forms a bloody red Moon in the night sky.
Eclipse will start at 20:30. and ends shortly before midnight, with a 62-minute period starting from 21:41, said Frank Florian, director of the planetarium at Telus World of Science, on Monday Interview with CBC Radio & # 39; s Edmonton A.M..
"It does not happen at three in the morning or something like this, so it's an opportunity for people to look outside and look at this red moon in the sky," said Florian.
During the lunar eclipse, the Moon passes through the shadow that is emitted by Earth into space. A complete eclipse, visible only to half of the world, occurs when the central dark part of the shadow shades the entire surface of the Moon, leaving a glowing red ring.
Common lunar eclipses tend to occur about every three years, but the event of this weekend is second to a relatively fast sequence, says Florian.
However, not many people were able to enjoy the last one that was seen in Edmonton in January 2018.
"It really happened early in the morning, about four in the morning, so there were not so many people on the street," he said.
– And it was also minus thirty. So, it was a really cool eclipse.
The World of Science Telus will hold events that are eclipsed from 17:30. on Sunday, including opportunities for viewing the night sky from the RASC Observatory and other telescopes to be installed. IMAX film First person, about the mission of Apollo 11, will work, and in the Seydler dome there will be special shows that explain the "geometry of eclipses", both sunny and moonlight.
Florian noted that the partial solar eclipse that was observed in Edmonton in August 2017 was a particularly noticeable event, mainly because the moon that passes in front of the sun is much less likely.
"If we want to see one in Edmonton, a complete solar eclipse, we will have to wait until 2044, in the month of August, at the beginning of the evening," he said. "As you can see, these things are much less common."
Lunar eclipse does not require people to travel outside the city, and Florian said it would help.
When the moon is full, he throws a lot of light that creates his own light pollution, concealing some of the weak stars, he said. But during the full darkness the moon is darkening – and the sky is growing.
"You will be able to see all the stars around the red moon silhouette, which makes it a very beautiful view."
