It's being hailed on social media as the "super blood wolf moon", though it's not really different from any other total lunar eclipse. For the keen sky-watchers the lunar disk will appear a few percent larger and brighter than usual making it a handsome sight to soak in and a great photo opportunity.
A "wolf moon" is what Native Americans call the year's first full moon.
As NPR's Rebecca Hersher has reported, the moon will get its shadowy revenge in a few years: "There will be solar eclipses visible from parts of the contiguous USA on October 14, 2023, and April 8, 2024". The name can be traced to earlier times when wolves would gather to howl at the moon during an unusual event.
The viewing in front of Union Station begins at 9 p.m. and is free and open to the public.
Lunar eclipses occur when Earth passes directly between the sun and the moon, forming a ideal line. Many Christians believe scripture indicates a Blood Moon is a sign from God regarding the return of Christ. This year, the moon will be high in the sky, which makes it the best chance to watch an eclipse in years. On Jan. 20, the moon will be about 222,274 miles from Earth as a full moon.
Unlike a solar eclipse, you can look at a lunar eclipse.
Once the eclipse is over on Sunday you won't get another glimpse of a Super Blood Wolf Moon until November 8, 2022.
Joel 2:31, "The sun shall be turned into darkness, and the moon into blood, before the great and awful day of the Lord come". Most colors on the spectrum are blocked, but red usually makes it through, effectively projecting all of Earth's sunrises and sunsets onto the moon's surface like a celestial cinema.
Although it is set to be a late Sunday night, there is no shortage of activities inside the centre in the lead-up to the eclipse. "It not only is a supermoon and it's a total eclipse, but the total eclipse also lasts pretty long".
Parents "can keep their kids up maybe a little bit later", said, Hartigan, who will catch the lunar extravaganza from Houston.
The sunlight passes through Earth's atmosphere, which filters out most of the blue light. January's full moon was referred to as the Wolf Moon.
The moon rises the evening of January 30th, 2018 along the St. Petersburg waterfront.
According to the Irish Astronomical Association, which is based in Northern Ireland, you won't need any special telescope to observe the eclipse, but a pair of binoculars will allow you to view the changing colours as it develops.
Sunday will mark the final time a lunar eclipse and a supermoon occur at the same time until May 2021.
