Total lunar eclipse to occur on Sept. 27

A total eclipse of the moon will begin on Sunday night, September 27, 2015, peak at 10:47 PM Eastern Daylight Time, and end at 12:27 AM Monday morning, scientists at NASA‘s Goddard Space Flight Center in Greenbelt, Md., report.

Approximate circumstances of the eclipse (from NASA / Goddard)

Circumstances of the lunar eclipse:

  • Partial umbral eclipse begins (U1): 9:07:12 PM EDT on September 27
  • Total eclipse begins (U2): 10:11:11 PM EDT
  • Greatest eclipse: 10:47:09.1 PM EDT
  • Total eclipse ends (U3): 11:23:07 PM EDT
  • Partial eclipse ends (U4): 12:27:06 AM EDT on September 28

The entire eclipse (P1–P4) will be visible in Maryland and Illinois, while people in the westernmost states will see it at moonrise Sunday evening. The eclipse will be visible in the early morning hours in Europe, Africa, and the Middle East, and won’t be visible at all from Australia or China. Watch it on NASA-TV, beginning at 8 PM Eastern.

Blood moon

The moon will be a harvest moon for folks in the Northern Hemisphere, as it is the full moon that occurs nearest the autumnal equinox.

The eclipse also marks the fourth and final total eclipse of a lunar tetrad—four straight eclipses at intervals of six lunar months. The other eclipses in this lunar tetrad occurred on April 15, 2014; October 8, 2014; and April 4, 2015.

Imagine if you were standing on the moon. What would you see? Watch this video and describe what would happen in your sky.
