As you have no doubt heard, we are expecting a lunar eclipse on September 28, 2015
It will be a total eclipse; making it what’s called a “Blood Moon”. It is called a Blood Moon due to the reddish colour it appears to take on when the Earth moves between the Sun and the Moon. The reason why the Moon takes on a reddish color during the total eclipse is a phenomenon called Rayleigh scattering. It is the same mechanism responsible for causing colorful sunrises and sunsets and the sky to look blue.
These total lunar eclipses are considered quite rare. Only 1 in 3 Lunar eclipses are total eclipses and only about 4 to 5 lunar eclipses can be seen from any one place on the earth within a decade. It is only every once and a while, we have 4 total lunar eclipses in a row. This is called a Lunar Tetrad. The total lunar eclipses happen 6 months apart in the Tetrad.
The full moon on Sept 27/28 is also a Supermoon, meaning that it is the closest to the earth as it turns into a full moon. According to NASA, they have only occurred 5 times in the 1900’s and it will not happen for another 18 years, on October 8, 2033
Other fun facts about the Total Lunar Eclipse on Sept 27/28:
It will happen on Harvest Moon, which is the full moon closest to the September Equinox.
It is part of the Lunar Saros Series 137. Saros cycles are 18 years in length.
