If the skies are clear after sunset on Sunday, Sept. 27 and you live in the Americas, head outside and witness the last total lunar eclipse until 2018. Or better yet, pop some popcorn, stay warm and cozy and watch the eclipse with HNGN!

The moon will be at perigree (the closest point to the Earth), so the moon will appear 13 percent larger than the last eclipse in April, according to a press release from Sky & Telescope. Easterners have the best view and can see the eclipse during every stage. Those in the west will see the eclipse as it starts its progression. South America can check it out later in the night and those in Europe and Africa will get a peek in the early morning of Monday, Sept. 28.

According to Sky & Telescope:

"The first 'penumbral' stage begins when the moon's leading edge enters the pale outer fringe of Earth's shadow: the *penumbra*. But the shading is so weak that you won't see anything of the penumbra until the moon is about halfway across it. Watch for a slight darkening to become apparent on the Moon's celestial east side: its lower left side as seen from North America."

"The second stage is 'partial eclipse.' This begins much more dramatically when the moon's leading edge enters the 'umbra,' Earth's inner shadow where the sun is completely hidden. With a telescope, you can watch the edge of the umbra slowly engulfing one lunar feature after another, as the entire sky begins to grow darker.

"The partial phase will last just over an hour. As its end approaches, only a final bright sliver remains outside the umbra. By this time the rest should already be showing a dim, foreboding reddish glow.

"The third stage is 'total eclipse,' beginning when the last rim of moon slips into the umbra. But the moon won't black out: it's sure to glow some shade of intense orange or red."

"'That red light you see on the moon is sunlight that has skimmed and bent through Earth's atmosphere and then continued on through space to the moon,' says Alan MacRobert of Sky & Telescope magazine. 'In other words, it's from all the sunrises and sunsets that ring the world at the moment.'

"'Picture it from the point of view of an astronaut standing on the Moon,' says MacRobert. 'They would see the dark Earth in the sky thinly ringed with brilliant orange from the Sun hidden behind it. The ring is bright enough to illuminate the lunar landscape an eerie red.'"
