Canadians may want to turn their eyes to the night skies on Monday if they want to see the moon pass closer to the Earth than it has in almost 70 years.
According to NASA, the so-called 'supermoon' will be the closest full moon to earth since 1948, and it won't be as close again until 2034.
The moon will be at its closest just before dawn on Monday, but will be almost equally visible Sunday and Monday nights.
The space agency says at that moment, the moon can appear larger and reflects up to 30 per cent more light on Earth than when it's at its farthest point of orbit.
But it says casual viewers are not likely to notice a difference.
Randy Attwood of the Royal Astronomical Society of Canada points out that the term "supermoon'' was not coined by astronomers and that "astronomically, it's not much of an event at all.''
