Final supermoon of 2014 will appear over Vancouver's skies tonight

Dec 19 2017, 8:00 pm

This summer’s trio of massive supermoons will conclude with tonight’s event beginning just before sunset.

The moon appeared full below the horizon in the east earlier this evening at 6:38 p.m., but it will still be very large throughout the evening, beginning at moonrise (94°E) at 7:20 p.m before setting (270°W) at 7:32 a.m.

Clear night skies will allow residents across Metro Vancouver to view Monday night’s and Tuesday morning’s final supermoon. It will be 14 per cent larger and 30 per cent “brighter” than the usual full moons.

The moon will be at its ‘Perigee’ stage, a term that indicates when the moon will be at its closest point in its elliptical orbit around Earth. This stage occurs approximately every 13 months.

Perigee events mean the moon could be as close as 356,500 kilometres away from Earth, while a moon in the ‘Apogee’ stage indicates the moon is at its farthest point away from the planet – as far away as 406,500 kilometres.

This summer’s two other supermoons were on July 12 and August 10, with the latter being the largest of the three.
