The moon is a familiar sight in our sky, brightening dark nights and reminding us of space exploration, past and present.
But the upcoming supermoon —on Monday — will be especially ‘super’ since it’s the closest full moon to Earth since 1948. We won’t see another supermoon like this until 2034.
The moon’s orbit around the Earth is slightly elliptical, so sometimes the moon is closer and sometimes it’s farther away.
When the moon is full as it makes its closest pass to Earth it is known as a supermoon. At perigree—the point at which the moon is closest to Earth—the moon can be as much as 14 percent closer to Earth than at apogee, when the moon is farthest from our planet.
The full moon appears that much larger in diameter and 30 percent brighter.
Unfortunately cloudy conditions are expected for the Jeffreys Bay area, which will make it difficult to view the supermoon.
