Connecticut residents will have their eyes peeled to the sky Sunday night as the “supermoon” makes its only appearance in 2017.

The full moon will begin at 10:36 a.m., Sunday, in Connecticut. The supermoon will reach its perigee —the closest point in its orbit around the Earth — at 3:45 a.m. the following day. At its perigee, the moon will be just 222,135 miles from Earth, nearly 16,000 miles closer than it normally is throughout the year, according to NASA.

By NASA’s calculations, the moon will appear as much as 14 percent bigger and 30 percent brighter to many viewers around the world.

The viewing for the supermoon might not be optimal though, as the National Weather Service is calling for limited visibility with a partly cloudy evening Sunday.

A supermoon occurs when there is a full moon at or near the point where the moon reaches perigee.

Though this event is actually the fourth supermoon of 2017, the first three were not visible to the naked eye because they occurred during a new moon, when the darkened face of the moon is facing Earth.

If you’re unable to see the supermoon, you won’t have to wait long for another opportunity. The next supermoon will occur just after the new year on Jan. 2.
