Triple lunar show

On Wednesday, most of the world will be able to see not only a blue moon, a supermoon and a total moon eclipse. This unusual event, a triple show, has not occurred since 1982 and the next will only occur in 2037.

The eclipse will look better in the western half of the United States and Canada before the moon sets in the early hours of Wednesday and in Asia when the moon rises at night. The blue moon is the second full moon in a month.

A supermoon is a full moon particularly close to Earth. The total eclipse of the moon gives the satellite an orange tone.
