What makes this a particularly rare astronomical event is that this is taking place at the same time as another celestial event: a lunar eclipse. During a lunar eclipse, the Earth will line up directly with the sun and moon, or to put it more scientifically, “the moon is moving into the shadow of the Earth.” The total result is that the moon will appear not only 14 percent larger and 33 percent brighter than a regular full moon, but also have a copper-red colour, hence the term “blood moon.” The south pole in particular will appear brighter.
In an article in Space.com (“Sunday’s ‘Supermoon’ Total Lunar Eclipse: When and Where to See It” (September 22, 2015), Joe Rao writes:
On the evening of Sept. 27, 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.
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. [Visibility Maps for the Supermoon Lunar Eclipse (Gallery)]
The Sept. 27 event is therefore being called a "supermoon eclipse." The last such eclipse happened in 1982, and the next won't occur until 2033.In this video, by Space.com. you can learn more about the total eclipse of the Harvest Moon from NASA’s Jet Propulsion Laboratory in Pasadena, California. Totality begins here in the east at 10:11 p.m. and ends at 11;23 p.m. (EDT). If you can’t see it in the sky, you can watch it online here.
