Blood Moon Lunar Eclipse: Weather Forecast For Metro Detroit

MICHIGAN — Rainy weather Sunday night might cost metro Detroiters the chance to see the first of two blood moons this year. The Lunar Eclipse was expected to start around 10:28 p.m., just as meteorologists said there's a 50 percent chance of rain under heavily clouded skies in the metro Detroit area.

The total eclipse was expected to happened at 12:11 a.m. Monday morning, before ending at 1:55 a.m. Meteorologists said Sunday night's rainy weather in metro Detroit was expected to carry over into early Monday morning, further hampering a chance to see the total eclipse.

Lunar eclipses only happen during a full moon, when the moon is opposite the sun in its orbit of Earth. In a total lunar eclipse, the sun fully illuminates the face of the moon. During an eclipse, the entire moon enters the darkest part of Earth's shadow.

The eclipse also comes as Astronomers on Thursday gave the world their first glimpse of a supermassive black hole in our Milky Way galaxy.

In a penumbral eclipse, the moon passes through the outer part of Earth's shadow, only slightly dimming the surface of the moon. In a partial eclipse, the moon enters Earth's darkest shadow, the umbra, causing some of the moon to darken significantly.

"Blood moon" is a descriptive rather than technical astronomical term, though The Old Farmer's Almanac says the phrase is "hyped" and that a fully eclipsed moon is orange, or copper-colored like a penny, but not blood red. The moon's color at totality can also vary depending upon the amount of dust, volcanic ash or other particulate matter in the atmosphere, and because of cloud cover, according to Space.com.

Weather permitting, the lunar eclipse is worth staying up late to watch, even if it isn't a supermoon.

"Supermoon" isn't an astronomical term either, but rather one coined by astrologer Richard Nolle, who calls a full or new moon a supermoon when it is at 90 percent of its closest point, or perigee, to Earth. Under Nolle's definition, four full moons meet supermoon criteria: a new or "stealth" moon on Jan. 14, full moons on June 14 and July 13, and a new moon on Dec. 23.

However, Fred Espenak, a retired NASA astrophysicist who worked at the Goddard Space Flight Center, uses slightly different criteria. He says the May flower moon is the first of four supermoons in 2022. He also counts the June 14 and July 13 full moons as supermoons. Unlike Nolle, Espenak says the Aug. 12 full moon will be a supermoon (bad news for Perseids meteor shower fans, because the supermoon and the peak of the summertime favorite coincide).

Either way, a supermoon isn't bigger, and it doesn't even look that much bigger in the sky when compared to a normal full moon. While it can look larger when it's close to the horizon, that's due to "the circuitry in your brain," according to Universe Today which explained "it's an optical illusion … so well known that it has its own name: Moon illusion."

Although most often called the full flower moon, the May full moon is also known as the corn planting moon and the milk moon in the United States. In Asia, it is known as the Vesak Festival Moon because it corresponds with Buddha Jayanti or Buddha Purnima, a Buddhist holiday that marks the birth, enlightenment and death of Gautama Buddha.

The actual date of the Vesak festival depends on the calendar used in different countries and regions, but generally falls on or near the day of the May full moon.

If you miss the eclipse this month, the second 2022 total lunar eclipse on Nov. 8 will be visible across the Americas, Oceania and Asia.
