By Joe Rao, SPACE.com Skywatching Columnist, Sept. 27, 2015 – Later this evening, the moon will once again become immersed in the Earth’s shadow, resulting in a total lunar eclipse — the fourth such event in the last 17 months,
As with all lunar eclipses, the region of visibility for Sunday’s blood-moon lunar eclipse will encompass more than half of our planet. Nearly 1 billion people in the Western Hemisphere, nearly 1.5 billion throughout much of Europe and Africa and perhaps another 500 million in western Asia will be able to watch as the Harvest Full Moon becomes a shadow of its former self and morphs into a glowing coppery ball.
You can watch the harvest moon lunar eclipse live in a webcast by the Slooh Community Observatory. You can also watch the total lunar eclipse on Space.com, courtesy of Slooh. The lunar eclipse will also feature the “biggest” full moon (in apparent size) of 2015, since the moon will also be at perigee on the very same day ─ its closest point to the Earth ─ 221,753 miles (356,877 km) away.

Tonights event is therefore being called a “supermoon eclipse.” The last such eclipse happened in 1982, and the next won’t occur until 2033.
