Partial Eclipse September 18th 2024

September 17th/18th sees a partial lunar eclipse. In London, the peak of the eclipse will be visible around 3:45 a.m. BST on September 18, while it was on the 17th September in the USA.. And it’s also a supermoon when the moon is at its closest to the Earth.. Sorry, you are unlikely to get this on time!

Could ancient people’s predict eclipses? Well, lunar eclipses are relatively easy to predict, while solar eclipses are difficult. But it is likely that Babylonian and Assyrians astronomers could.

There are plenty of people who believe that eclipses can be predicted by Stonehenge. And it certainly can be used that way, but this doesn’t mean it was. A series of stones, and posts in concentric circles with sight lines to innumerable features on the horizon offers many ways of making calculations which combined with observations over a long period COULD predict, predictable celestial phenomena. Doesn’t mean they were. So it is very difficult to say what they were capable of, and only the most obvious alignments can be certainly confirmed.

This Washington Post article below suggests the Loughcrew Cairns near Dublin were built about the time of a total eclipse, and that one of the stones with complicated carvings on may show a lunar eclipse. If you look at the sketch of the stone above, you will see the biggest circle, near the middle, may represent the moon, and it obscures the circle behind it which may represent the sun.

What is striking is how can they say it was built around the time of a total eclipse and make that seem significant because there is no way archaeological dating is accurate enough to give any idea whether it was built for a particular day. Also, there are many more circles and objects on the large stone, and to pick two out to prove what you want it to prove, is not proof. We are left with the intriguing possibility, but it is no more than that.
