A "supermoon" rises this weekend.

The biggest and brightest full moon of the year graces the sky early Sunday as our celestial neighbour swings closer to Earth than usual. 

While the moon will appear 14 per cent larger than normal, most sky watchers won't be able to notice the difference. Still, astronomers say it's worth looking up and appreciating the cosmos.

The moon will be closest and turn full around 4:30 a.m. PT or 7:30 a.m. ET, which means people living on the West Coast are more likely to get a better view.

As in any supermoon event, high tides are forecast because of the moon's proximity, but the effect is expected to be small. 

Forget about the myths that swirl every time a supermoon appears. There's no link to higher crime or bizarre behaviour. Scientists say that's just lunacy.
