Supermoon of 14 November is the closest Moon to Earth since 1948

5 of the best places to view the supermoon

An unusually large and bright Moon will adorn the night sky next Monday - the closest "supermoon" to Earth in 68 years and a chance for dramatic photos and spectacular surf.

"Since the moon's orbit is elliptical, one side (perigee) is about 30,000 miles closer to Earth than the other (apogee)".

Brosch explained that to have a Super Moon, the closest approach has to happen when the Moon in its orbit around the Earth happens to be nearly in line with the Earth-Sun direction, on the side of its orbit where it is away from the Sun, thus its visible disk is fully illuminated. Such a combination would not re-occur until 2034.

The point when the Moon is closest to Earth is called the perigee, while the point most distant to Earth is the apogee.

Fans of astronomy and night photography take notice; the largest, brightest supermoon in almost 70 years will fill the skies November 14.

The best views are to be found in areas with the least light pollution so head for the countryside or to the sea as the effect is most pronounced when the moon is viewed near the horizon.

The term supermoon is not an official astronomical name. The key to capturing the Supermoon includes good equipment, scouting a location ahead of time, and clear weather. "The perigee moon will indeed be bigger".

"If you think about the orbit of the moon around the earth, it is not a ideal circle, it's an ellipse", Dann said. A super moon also looks about 30% brighter.

This pattern occurs because the moon orbits the Earth. As pointed out above, this is the brightest supermoon since 1948. You can watch the Moon as it progress out of the sky. This month, the Moon reaches perigee on November 14 at 356,511 kilometers distant, 2 hours and 22 minutes before Full. That's the closest full moon of the year, or every 14 months to be precise.

The moon will become full at 13:52 GMT on Monday, so the best time to view it in Ireland will be when the sun is setting in the late afternoon.

But to the casual observer, the moon will look little different from any other full moon. So, if you gaze at the Moon in the north-northwest when it is full shortly before 3am local time in New Zealand on 15 November, note that it will be 33.8 arcminutes in diameter.

If you're not an early riser in the United States, no worries.
