For more than an hour this coming Saturday night, when the Earth passes between the Sun and the moon, only a fraction of the usual amount of light will reach the natural satellite.
Bent by the Earth’s atmosphere, the only light hitting the full moon will be hints of all the world’s sunrises and sunsets.
Weather permitting, Canadians from coast-to-coast will be able to spot the effects of the rare alignment beginning at approximately 8 p.m. ET, when the Earth’s outer shadow, or penumbra, begins to creep across the surface of the moon.
The real action begins at 9:14 p.m. ET, when the Moon advances into the Earth’s umbra, or full shadow.
From that moment, a dark scallop will envelop the moon, perhaps turning it one of the shades of crimson that petrified ancient civilizations.
Totality lasts until approximately 11:45 p.m. ET, during which time anyone with a clear view should be able to see the effects without the aid of a telescope.
