LunarEclipse

Sunday night September 27 there will be the fourth in a series of four total lunar eclipses (known as a tetrad) set about six months apart. This series began April 15 2014 with the subsequent events occurring October 8 2014 and April 4 2015.

The 21st century will see eight of these tetrads, while from 1600 to 1900 there were none.

There won’t be another total lunar eclipse until 2018.

The fourth eclipse will also occur during a Supermoon (the closest full moon of the year) and a Harvest Moon (the full moon closest to the fall equinox).

The full eclipse of the moon will last more than an hour and be visible from North and South America, Europe, Africa and western Asia.

9:07 PM EDT – The partial eclipse begins
10:11-11:23 PM EDT – Total eclipse time
12:27 AM EDT – The visible part of the eclipse ends and the Moon looks normal
Viewers in the Eastern U.S. will see the entire progression. Viewers in the western U.S., sunset is about 18:57 and dusk is about 19:23 is so the Moon may rise in partial eclipse.

If you have weather challenges, Nasa.gov and Space.com will have live coverage. The Slooh Community Observatory (online observations from a global network of telescopes) will offer high-definition views at slooh.com.
