Clear skies across Maine and New Brunswick will make for ideal viewing of a rare phenomenon Sunday night – a total eclipse of a so-called "supermoon."

When the full moon makes its closest approach to Earth (perigee) it appears 14 per cent larger and about 30 per cent brighter than when it is at its furthest point.

As the moon is eclipsed by the Earth's shadow it may turn a deep rusty red-orange, due to sunlight being scattered by the Earth's atmosphere. So we have the "Supermoon" and "Blood Moon" happening simultaneously Sunday night.

This spectacular lunar double feature will begin with a partial eclipse at 9:07 p.m. Eastern Time. The best viewing of the eclipse should be between 10:11 and 11:23 p.m., with the full eclipse occurring around 10:47 p.m.

The last time these two events coincided was in 1982 and it won't happen again until 2033.  So grab your jacket, a friend, a camera or a telescope and enjoy this rare treat–the total eclipse of a super moon.
