Don't miss Sunday's rare celestial event: How to see the supermoon, full moon and lunar eclipse
Most all of North America, South America and Africa will have a chance to see something truly amazing on Sunday when three celestial events – a full moon, a supermoon, and a lunar eclipse – will coincide for a few hours.
The majority of the viewing area will see the full eclipse for about an hour, but where you are in the world will determine just how late you need stay awake (or how early you need to get up) to take it all in.

According to USA Today, the West Coast of the United States and Canada have the best timeframe. Folks in Vancouver and Los Angeles can enjoy the sight over dinner with the full eclipse happening around 7:11 p.m. It will last one hour and 12 minutes.
Eastern U.S. cities, including New York and Atlanta, will have to wait until 10:11 p.m., and South American cities such as Rio will have to wait a further hour.
Rare supermoon eclipse: What you should know
Viewers in Europe and Africa will have to get up early on the morning of the 28th, with the full eclipse peaking at around 3:11 a.m. in London and Tangier and about 4:11 a.m. for Madrid and Cape Town.
Weather conditions will also play a significant role in who is able to catch a glimpse of the historic sight.
"The current forecasts show that a stubborn low off the East Coast may lead to cloud cover blocking the eclipse from view over the Middle Atlantic region and Southeast," weather.com meteorologist Quincy Vagell said. "A storm system in the north-central states may also bring disrupting clouds from the northern Plains back into the central Rockies. Elsewhere, high pressure is expected to bring good viewing condition to parts of New England, the Midwest, Southwest and the West Coast."
So what does it take for these three event to coincide?
The most common of the three, of course, is the full moon, which happens every month as the moon makes its orbit around the Earth. The orbit isn't a perfect circle, so at times the moon is closer and seems bigger in the sky, a phenomenon known as a "supermoon."

The point in the moon's orbit that brings it closest to Earth is known as perigee, and the perigee for September will come at a time when the moon is passing through the Earth's shadow, a lunar eclipse.
Light still reaches the moon during a lunar eclipse, but it has to pass through the Earth's atmosphere first. Red light tends to make it through easier and the moon takes on a reddish glow nicknamed the blood moon.
The full moon, supermoon, blood moon combo has only happened five times since 1900, with the last coming in 1982, Space.com reports. If you decide to skip this one, you won't get the chance to see it again until 2033.
