The Last Super Blue Moon until 2037 Rises Tonight

A second full moon, a once-in-a-lifetime occurrence, will be visible to skywatchers in August, which is almost done.

In addition, the full moon that rises on Wednesday, August 30, will be unique because it will combine a supermoon with a blue moon to form a "Super Blue Moon."

However, the moon won't appear to be very blue at this hour. The phrase "Blue Moon" refers to either two moons happening in the same calendar month (as in this instance) or the third full moon of a season with four full moons, and has nothing to do with color.

A supermoon, meanwhile, refers to a full moon that occurs when the moon is closer to Earth in its orbit, resulting in a slightly larger and brighter appearance.

According to In the Sky, from New York City, August's second full moon will begin rising over the eastern horizon in the Aquarius constellation just after sunset tonight at around 7:10 p.m. EDT (2310 GMT).

The Super Blue Moon will then set just before sunrise on Thursday, Aug. 31 at around 06:46 EDT (1046 GMT).

And if weather is poor in your area, no need to fret: You can watch the Super Blue Moon with a free livestream hosted by the Virtual Telescope Project.

The exact moment of the full moon is defined as the moment at which it is exactly opposite the sun. For the Super Blue Moon, this 180-degree separation from the sun with happen at around 21:36 EDT (0336 on Thursday, Aug. 31), according to NASA, and this is when it will be at its biggest and brightest.
