The Skywatchers are seeking treatment this week when a full moon, supermoon and total solar eclipse occur on the same day - a rare trifecta of the moon, according to NASA.
A celestial spectacle will occur just before dawn on Wednesday, when the full moon and the brightest moon of the year turn red as it glides completely under the Earth's shadow.
With the weather permitting, a total lunar eclipse will be seen across the Western United States, western Canada, Mexico, much of Central America, parts of South America and Asia along the Pacific Rim.
"People in Hawaii and the Aleutian Islands will see every eclipse - it will be a spectacle for them," Bill Cooke, head of NASA's Environmental Environment Office in Huntsville, Alabama, said in a statement.
The eclipse coincides with the "supermoon," the full moon at its nearest point on Earth in its orbital orbit. The full moon of May is sometimes known as the "flower moon" in traditional history because it is usually the time of year when spring flowers appear.
And because the eclipse is sometimes called "blood months" as the moon darkens and turns a comforting red as it passes into the Earth's shadow, this week's sky-viewing event is called "the most beautiful blood month."
A total lunar eclipse will be the first to occur on a supermoon in about six years, according to NASA. In the future the full sun exposure in the U.S. It will be May 16, 2022.

Eclipses occur when the Earth moves between the sun and the moon, blocking sunlight from falling on the moon. The eclipse will begin on Wednesday at 4:46 a.m. ET.
When it completely slides in the shadow of the Earth, the moon will appear red, known as the whole, from 7:11 to 7:26 a.m. ET.
Unlike solar eclipses, astronomers do not need any special equipment to securely view a celestial spectacle. And for those who are in areas where the eclipse will not be visible, it will still be possible to capture live action online.
The European Space Agency and the Commonwealth's Scientific and Industrial Research Organization of Australia will host a live broadcast on ESA Web TV. The Virtual Telescope project, based in Italy and partners with robotic telescopes worldwide, will also broadcast the event on its website.
