Two weeks after casting its shadow across the Americas during an annular solar eclipse, the moon will swing around to skim through the northern edge of the Earth’s own shadow on Saturday, Oct. 28.
Eclipses of the sun and moon usually come in pairs. A solar eclipse is almost always accompanied by a lunar eclipse two weeks before or after it, since in two weeks the moon travels halfway around its orbit and is likely to form another almost-straight line with Earth and the sun.
This month will be no exception. Two weeks after casting its shadow across the Americas on Oct. 14 during an annular solar eclipse, the moon will swing around to barely skim through the northern edge of the Earth’s own shadow on Saturday, Oct. 28.
This will be almost like the lunar eclipse in May, though the moon passes not quite so wide of the center of the Earth’s shadow and manages to give the Earth’s dark umbra a glancing blow; an underwhelming postscript to the annular eclipse of the sun that was staged for North Americans exactly two weeks earlier.
