Super moon to be seen on Sunday night

While there is no formal definition of a supermoon, it's typically considered a full moon that occurs at perigee.

It's worth noting that a supermoon technically occurs during a new moon, too, but that phenomenon usually isn't referred to as a supermoon since new moons are not visible in the night sky.

The difference is noticeable for close observers - particularly if the moon is near the horizon, where it can be compared with terrestrial landmarks. The liberal definition would be a full or new moon that's at or near its closest approach to Earth in its orbit.

Monday's supermoon will appear about 14 per cent bigger than if it were at its farthest away point in its orbit and will shine up to 30 per cent brighter.

The moon will look a little bigger and brighter than usual this weekend.

You'll be able to watch the supermoon starting on Sunday Dec. 3.

Mark your calendars: a series of three supermoons will appear on the celestial stage on December 3, 2017, January 1, 2018, and January 31, 2018.

The average distance between the moon and earth is 3,84,000 km, but at perigee, it is 3,56,000 km and at apogee, it will be 4,06,300 km.

"The supermoons are a great opportunity for people to start looking at the Moon, not just that once but every chance they have!" says Noah Petro, a research scientist from NASA's Goddard Space Flight Center.

If you're clouded out on Sunday, you can still get into the supermoon spirit on Sunday with streaming video from the Virtual Telescope Project or the Slooh online observatory.

A supermoon occurs when there is a full moon at or near the point where the moon reaches perigee.

The Jan. 31 supermoon will feature a total lunar eclipse, which will cause the moon to take on a reddish hue, making it a "blood moon".
