There was delight for star gazers who observed a rare blood red "supermoon" in the early hours of this morning.
Two major events came together as a supermoon coincided with a lunar eclipse.
A supermoon occurs when the moon is in the closest part of its orbit to earth, meaning it appears larger in the sky.
David Moore of Astronomy Ireland said his organisation had received pictures of it from all around the country.
"We ran a watch ourselves from 2am to 6am at our headquarters in Blanchardstown.
"There were hundreds of people there in the small hours of the morning, far more than we expected," he said.
"They were treated to an incredible spectacle of nature."
Mr Moore said that there was a perfect sky with hardly a cloud in sight.
The total part of the eclipse was about an hour and ten minutes. That was when the moon was completely immersed in the Earth's shadow.
"The moon shouldn't be visible but thanks to our atmosphere, we do see it with this coppery red colour," Mr Moore said on RTE's Morning Ireland.
