Weather permitting stargazers will get a rare two for one treat tonight — a total lunar eclipse combined with a so called supermoon.
When a full or new moon makes its closest approach to the Earth it's called a supermoon because it appears slightly bigger and brighter than usual.
And as the moon is eclipsed by the Earth's shadow it can also turn a reddish colour, an eerie wonder known as a Blood Moon.
Tonight's celestial double feature will start shortly after 9 p.m. and is expected to last about three hours.
Experts say the timing of the eclipse will be good for most parts of Canada, but those on the West Coast will miss the initial stages because the moon will be low in the sky as the sun sets.
The next total eclipse won't happen until 2018, and the next total eclipse of a supermoon won't happen until 2033.
