Stargazers across Ireland will get a rare chance to see a rare blue supermoon tonight and tomorrow night.
But pesky clouds may scupper a chance of seeing the amazing sight over Donegal.
A ‘supermoon’ is when a full moon occurs around the time that the moon is closest to the Earth.
A blue moon occurring at the same time that a full moon is a supermoon is rare, and will not happen again until 2037.
The moon’s distance from the earth can vary by around 15%. When it is at its closest, and when a full moon happens, it causes a change in brightness of 30%, according to Astronomy Ireland.
Astronomy Ireland said that full moons at this time of year are very low in the sky, making them ideal for people to capture photos of the moon lining up with landmarks.
David Moore of Astronomy Ireland said the best time watch the moon will be as it rises and as the sun sets.
He encouraged people to send their images to Astronomy Ireland where they will be archived in the National Library.
However, visibility may be affected later as a band of rain tracks across the country with some heavy or thundery falls possible.
Tomorrow night will be largely dry with clear spells and just isolated showers, although cloud will build from the west later.
