Total Lunar Eclipse: How to Watch Sunday’s Rare ‘Super Blood Moon Flower’

A spectacular full moon will grace the night sky on Sunday evening. It not only marks a super moonbut also a Moon of blood — thanks to a lunar eclipse.

The last total lunar eclipse occurred a year ago on May 26, 2021. If the weather is clear, millions of sky watchers in the Americas, Europe and Africa will be able to see the total lunar eclipse in the night of May 15 to 16.

What is a blood moon?

According to NASA, a Moon of blood occurs during a total lunar eclipse, when the Earth is positioned directly between the moon and the sun, obscuring the moon from sunlight.

During totality, the moon will be a faint reddish glow, as red wavelengths of sunlight filter through our planet’s atmosphere onto the moon’s surface. At different times during the eclipse, it might also appear to take on shades of orange, yellow, or brown.

“When this happens, the only light that reaches the moon’s surface comes from the edges of Earth’s atmosphere,” the space agency explains. “Air molecules in Earth’s atmosphere scatter most of the blue light. The remaining light reflects off the moon’s surface with a red glow, causing the moon to appear red in the night sky.”

This month’s full moon is also a supermoon, meaning it appears slightly larger and brighter than usual as it sits at its closest point to Earth in its orbit, known as the name of perigee.

It is also the flower moon, one of the names given to the May full moon because of the abundance of flowers associated with spring in the northern hemisphere. It has also been called the corn planting moon and the milk moon.

How to watch

Unlike a solar eclipse, which requires special glasses to prevent eye damage, a lunar eclipse can be viewed safely with the naked eye, but binoculars or a telescope would also enhance the viewing experience.

The visible part of the eclipse will begin around 10:30 p.m. ET on May 15, according to NASA, when the moon enters Earth’s shadow. Totality, when the moon is completely covered by our planet’s shadow, follows around midnight and lasts about an hour and a half.

It will end around 2 a.m. ET.

According to NASA, viewers in the eastern United States will see the eclipse begin with the moon well above the horizon, while those in the middle of the country will see it begin about an hour and a half after dark. the night. On the west coast, the moon will rise when totality is already underway, so the best views will be to the southeast.

So viewers on the east coast will be able to see the event high in the sky, but those on the west coast should seek an open place to watch. According to time and date, this will be the longest prime-time total lunar eclipse on the West Coast this century.

But don’t worry if you don’t have an optimal view: NASA will broadcast the event live, show views from around the world and answer viewers’ questions about the phenomenon.
