Total Eclipse of the Harvest Moon   
       
   Sept. 22, 2015: In the days before light bulbs, farmers relied on moonlight to   
   help them harvest their crops.  Many crops ripen all at once in late summer   
   and early autumn so farmers found themselves extremely busy at this time of   
   year. They had to work after sundown.  Moonlight became an essential part of   
   farming, and thus, the Harvest Moon was born.   
       
   According to folklore, the Harvest Moon is the full Moon that falls closest to   
   the autumnal equinox, the hectic beginning of northern autumn. In 2015, the   
   Moon is full on Sept. 28th, less than a week after the equinox of Sept. 23rd.   
   The coincidence sets the stage for a nice display of harvest moonlight.

   But wait.  This year's Harvest Moon is not like the others.  It's going to be   
   eclipsed.   
       
   On Sep. 27-28, 2015, the super Harvest Moon will pass through the shadow of   
   Earth, producing a lovely amber total lunar eclipse.   
       
   On the night of Sept. 27 and into the early hours of Sept. 28, the full Moon   
   will glide through the shadow of Earth, turning the Harvest Moon a golden-red   
   color akin to autumn leaves.   
       
   The action begins at 9:07 PM Eastern Time on the evening of Sept 27th when the   
   edge of the Moon first enters the amber core of Earth's shadow.  For the next   
   three hours and 18 minutes, Earth's shadow will move across the lunar disk.   
       
   Totality begins at 10:11 PM Eastern Time.  That's when the Moon is completely   
   enveloped by the shadow of our planet.  Totality lasts for an hour and 12   
   minutes so there is plenty of time to soak up the suddenly-red moonlight.   
       
   The reason the Moon turns red may be found on the surface of the Moon itself.   
   Using your imagination, fly to the Moon and stand inside a dusty lunar   
   crater.  Look up. Overhead hangs Earth, nightside facing you, completely   
   hiding the sun behind it. The eclipse is underway.   
       
   You might suppose that the Earth overhead would be completely dark.  After   
   all, you're looking at the nightside of our planet. Instead, something amazing   
   happens.  When the sun is located directly behind Earth, the rim of the planet   
   seems to catch fire! The darkened terrestrial disk is ringed by every sunrise   
   and every sunset in the world, all at once. This light filters into the heart   
   of Earth's shadow, suffusing it with a coppery glow.   
       
   Back on Earth, the shadowed Moon becomes a great red orb.   
       
   One more thing: The full Moon of Sept. 28th occurs near the perigee of the   
   Moon's orbit-that is, the point closest to Earth.  This makes the Harvest Moon   
   a "supermoon."   
       
   The super Harvest Moon eclipse will be visible from the Americas, Europe, and   
   Africa.  It brings an end to a remarkable series of four consecutive total   
   lunar eclipses visible from North America-a so-called "tetrad." Perhaps the   
   heavens have saved the best for last.   
       
   If you live in the eclipse zone, mark your calendar for Sept. 27-28, and enjoy   
   the show.
