Skygazers are in for a treat this Sunday with a supermoon and a blood moon eclipse visible in the night sky, if the clouds stay away.

A Harvest Moon is the full moon closest to the autumnal equinox. The Northern Hemisphere will see the 2015 autumnal equinox coming on the 23 September, with the full moon on the 28 September being identified as the Northern Hemisphere's harvest moon.

This year's harvest moon will be the closest and largest full moon of the year which makes it qualify as a supermoon as it will turn fully approximately one hour after reaching lunar perigee (the moon's closest point to the Earth for the month).

The supermoon will also be staging a Blood Moon eclipse on the night of 27-28 September.

A blood moon is caused by light refracting through the edges of Earth's atmosphere and illuminating the moon.

The eclipse will be visible to the naked eye with the start of the partial eclipse just after 2am on Monday morning.

The total eclipse will start at 3.11am and will end at 4.23am.
