Super Blue Blood Moon 2018: What, when and where

The last Blue Moon occurred in July 2015 and in 2018, we'll experience two of them, a phenomena that won't happen for another 19 years. The second Blue Moon is slated to occur in late March.
The Blood Moon occurs because the Earth is passing between the Moon and the Sun, which gives the Moon a reddish tint to it. It's caused by light bending around the Earth because of gravity passing around a portion of the atmosphere, more commonly known as a lunar eclipse.
A Blue Moon combined with a Supermoon (when the Moon is at its closest point to Earth and appears to be 14 percent bigger and 30 percent brighter than normal) the rare phenomena is called a Super Blue Blood Moon happens. Supermoons generally only occur once every 14 months and will not happen again until January 2019.The last time all of these events occurred simultaneously in the Western hemisphere was 1866.
