Today's full moon, which will be the year's biggest supermoon and feature the first total lunar eclipse in more than two years, will be visible from most areas in Japan.
During the eclipse, the full moon will pass through the Earth's shadow. It appears red, known as a "blood moon," as light is scattered through the Earth's atmosphere, much like during a sunset. In addition, the moon will be at perigee, or the closest point to Earth in its orbit, making it appear about 7% larger than normal and 15% brighter, or a supermoon, according to astronomers. May's full moon is known as the "Flower Moon" since it occurs when spring flowers are in bloom.
The result, when taken together, is being called a "super flower blood moon."
