September's full moon arrives at 9:38 p.m. Monday, known as both the Corn and Harvest moon.
American Indians named it the Corn moon for coinciding with the crop's harvest, whereas the Harvest moon can fall in September or October, depending on which full moon is closest to the autumnal equinox, Sept. 23 this year.
It is the third of three consecutive "supermoons," as it coincides with lunar perigee, when the moon is closest to Earth in its orbit. Such a coincidence can make the moon look larger and brighter than when full moons are closer to apogee, their furthest point from Earth, though it can be hard to tell with the naked eye.
The celestial wonders don't stop there -- next month's full moon is not far from being considered a supermoon, and it coincides with a lunar eclipse that can give the moon a reddish hue, dubbed a "Blood Moon." It occurs the night of Oct. 7-8.
An earlier version of this post misstated the timing of the full moon. The Sun regrets the error.
