BLOOD MOON - Total Lunar Eclipse

[Admin]

Lunar Tetrad

Total lunar eclipses are rare – only about one in three lunar eclipses are total. About four to five total eclipses can be seen at any place on Earth in a decade.Lunar eclipses usually do not occur in any specific order. However, every once in a while, four total lunar eclipses happen in a row. This is called a lunar tetrad. The total lunar eclipses happen 6 months apart. There are at least six full Moons between two total lunar eclipses in a tetrad
The first three total eclipses in this lunar tetrad occurred on
April 15, 2014,
October 8, 2014,
and April 4, 2015
The last eclipse of the tetrad will occur on September 28, 2015.
All four total lunar eclipses are visible from most of the United States.
According to NASA, the current century – 2001 to 2100 – will have eight tetrads. The first tetrad of the 21st century took place in 2003, and the second will happen in 2014-2015. The first eclipses in each of these tetrads will occur between March and May.

Blood Moons may Look Red

In recent years, the term Blood Moon has become popular when referring to Total Lunar Eclipses. When the Earth eclipses a full Moon, the direct sunlight is blocked, but the sun's rays still light up the moon. This light, however, has travelled through the Earth's atmosphere first, and sometimes causes the totally eclipsed Moon to look red or brownish.
