I'll wait behind the moon



This size of moon doesn't happen often, the last time was 18 years ago.


Saturday night’s full moon, which will rise just after 8 p.m. in Vancouver, is going to be special — and not just because it will be the last full moon of the winter, coming on the eve of Sunday’s first official day of spring. No, Saturday night’s moon is going to be a supermoon, also known as a perigee moon.

A supermoon is bigger and brighter than an ordinary full moon. The reason: the moon’s orbit around the Earth is elliptical, not round. And so when the elliptical path passes closest to Earth — as will be the case Saturday night —a full moon becomes 14 per cent wider and 30 per cent brighter than an average full moon. Not since 1992 has the moon passed as close to Earth as it will tonight.
