THE FACT that dawn sunlight will beam into the passage grave at Newgrange tomorrow at the very moment that a full moon begins to pass out of a total lunar eclipse is a remarkable and rare coincidence, according to Prof Tom Ray, an astronomer at the Dublin Institute for Advanced Studies.

“It is the first time it has happened in about 450 years so that is a coincidence enough. The Tudors were in power in England at the time,” he said.

It is even more remarkable that light from the sun and the moon will appear together, with the first sunbeams at dawn coming just as the moon emerges from eclipse.

“That will happen at exactly eight minutes to nine. The two happen to coincide to within a minute.”

This kind of connection is unbelievably rare, Prof Ray said. “It would not have occurred since Newgrange was built.”


Of course, we all know that this was prophesised in thuh Babble

I'm not getting the distinction in rarities that the professor is making.

Newgrange * dawn * solstice * lunar eclipse  = once in 450 yrs

?? = not since Newgrange was built

If you were in the Newgrange chamber, you wouldn't see the moon. It would be setting behind you, with tons of rock and dirt between you and that horizon.

I take it that precession of the equinoxes does not affect sites such as Newgrange. The solstice dawn hapens at the same point on the horizon, no matter what day the solstice happens to be.

What's rare is the coincidence of the eclipse and solstice dawn. As the eclipse ends you'll just have enough time to get inside, scramble down the passage and turn around to see the sun light up the inside.

Mind you, you have to be lucky to win a place in there for the morning of the solstice. (There's a lottery of some sort, places are liable to be gazumped by visiting dignitaries etc etc) The rest of us mere peasants have to make do with the simulated dawn they do with electric lights six times a day on the tours.
