There is a total eclipse of the moon on the night of September 27-28, 2015. It happens to be the closest supermoon of 2015. It’s the Northern Hemisphere’s Harvest Moon, or full moon nearest the September equinox. It’s the Southern Hemisphere’s first full moon of spring. This September full moon is also called a Blood Moon, because it presents the fourth and final eclipse of a lunar tetrad: four straight total eclipses of the moon, spaced at six lunar months (full moons) apart. Phew!
The total lunar eclipse is visible from the most of North America and all of South America after sunset September 27. From eastern South America and Greenland, the greatest eclipse happens around midnight September 27-28. In Europe, Africa and the Middle East, the total eclipse takes place in the wee hours of the morning, after midnight and before sunrise September 28. A partial lunar eclipse can be seen after sunset September 27 from western Alaska, or before sunrise September 28 in far-western Asia.

When is the September 2015 moon exactly full? Generally speaking, we can say the moon stays full all night on September 27-28.
But, to astronomers, the moon turns full at a well-defined instant: when it’s opposite the sun in ecliptic longitude.
That instant happens on September 28, 2015 at 2:51 UTC. At our U.S. time zones, that places the precise time of full moon on September 27 at 10:51 p.m. EDT, 9:51 p.m CDT, 8:51 p.m. MDT or 7:51 p.m. PDT. At that time, because there’s an eclipse happening, the moon will be totally submerged in the Earth’s dark umbral shadow.
Meanwhile, because of the difference in time zones, this same full moon happens around local midnight (September 27-28) for Brazil and Greenland. It’s sunset (September 27) for far northeastern North America and it’s sunrise (September 28) in far-eastern Africa, the Middle East and European Russia.
Watch the full-looking moon on the night of September 27-28 to rise in the east as the sun goes down. Like any full moon, the Northern Hemisphere’s Harvest Moon will shine all night long. It’ll soar highest in the sky around midnight and will set in the west around sunrise.

Who will see the September 27-28 total lunar eclipse? The September 2015 full moon passes directly through Earth’s dark (umbral) shadow. The total part of this eclipse lasts for 72 minutes. A partial umbral eclipse precedes totality by some 64 minutes, and follows totality by about the same period of time, so the moon takes about 3 and 1/3 hours to completely sweep through the Earth’s dark shadow.
North America, South America, the Atlantic Ocean, Greenland, Europe, Africa and the Middle East are in a good position worldwide to watch the total eclipse of the moon. If you live in the Americas, the total eclipse happens after sunset September 27. In the world’s eastern hemisphere, the total eclipse happens after midnight and before sunrise September 28.
A very light penumbral eclipse comes before and after the dark (umbral) stage of the lunar eclipse. But this sort of eclipse is so faint that many people won’t even notice it. The penumbral eclipse would be more fun to watch from the moon, where it would be seen as a partial eclipse of the sun.
Who will see the partial lunar eclipse on September 27? A partial lunar eclipse may be visible in the haze of evening dusk on September 27 from the extreme northwestern portion of North America (western Alaska). A partial lunar eclipse might also be observed in the haze of morning dawn (September 28) from far-western Asia (Pakistan, Afghanistan, eastern Iran).

The moon moves from west to east across the Earth’s shadow. The horizontal yellow line depicts the ecliptic – Earth’s orbital plane projected onto the dome of sky. The greatest eclipse takes place on September 28, at 2:47 Universal Time (or for US time zones: September 27 at 10:47 p.m. EDT, 9:47 p.m. CDT, 8:47 p.m. MDT or 7:47 p.m. PDT).
