Total Solar Eclipse - 8 April in the USA.

[Ray Proudfoot 9,038]

The sun is 400 times larger than the moon so how is it possible for such a small object to cover the sun? By a quirk of nature the moon is 400 times closer to us. So they both appear around the same size to us on Earth.

But the moon’s orbit around Earth is not circular. It’s elliptical. Yesterday it was just 359,397km away. The closest it could be is 356,508km so yesterday was a close approach. Hence totality lasting over 4 minutes over a large area.

But when the moon is at apogee it’s at its furthest point from us at 405,500km and too small to completely cover the sun’s disc. That’s when annular eclipses occur.

So if the moon had a circular orbit and was positioned just 37,000km further away we’d never see total solar eclipses. Lucky eh? 😁

In our flight simulators the phenomenon is seldom correctly modelled...

FLIGHGEAR used to have the most comprehensive modelling, given it's detailled astronomical formulas...

The April 8 eclipse was poorly represented in XP12, MFS not that bad... I couldn't test it in either FG or ELITE though - not installed 🙂

Though the pictures of Monday's eclipse that I've seen show what it looked like, the stunning brilliance of the absolute black of the moon's disc surrounded by the bright absolute white of the angle hair fine corona and the diamond rings' flash is something that a camera can't capture.  If you've ever seen it you know what I'm talking about, for me it was so moving that I was laughing and crying at the same time.  I watched it all unfold laying flat on my back.

(Solar Eclipses are rare in the Southern latitudes).

I can’t think of any reason why they would be. Look at the available land mass in the southern hemisphere. Mostly water so fewer places where the path will cross populated areas.

[Fielder 3,726]

Yeah, you're right. I should  have said total eclipses are rare in the Southern latitudes, instead of just eclipses.

Eclipses are far more likely in the Summer when the sun is up longer. And the sun's orbit isn't a perfect circle. Summer in Northern Hemisphere happens when sun is farthest from the Earth and therefore it looks smaller. Small enough for a total eclipse.

The total eclipse is so different from anything we're used to that the experience is magical.  And it's beautiful.

It's very well worth doing a bit of travelling to see one, but I don't know if I'd get on an airplane.  Four hours in a car?  Totally fine. (heh!  See what I did there?  Totally accidentally of course.)

Three days later and I'm still feeling a sense of wonder.

Those who have never seen one might doubt how spectacular they are. I cannot imagine any feel the same after having witnessed one.

I found the coverage frustrating on BBC / CNN on Monday. Someone with suitable knowledge should have advised them to position a camera above the crowd on as wide angle as possible pointing SW so the shadow could be seen approaching. And then another camera taking in the ground but also including the sun so the whole scene was visible.

It was cloudy during the 11th August 1999 total solar eclipse from my viewpoint on the Devon-Cornwall border, but I can honestly say that it was one of the most amazing experiences of my life. Do not hesitate to attempt to see one if you have the opportunity to do so. I am already excited about the possibility of seeing totality in 2026!

57 years till the next solar eclipse in Guernsey. 😞

There is a partial solar eclipse in 2025 though. 

Next total lunar eclipse in 2025, 7th September.

You lucky! After the 2019 eclipse in Córdoba, we have to wait at least until 2187. The day after that I'd be turning 202 😂

Or I can book a trip to somewhere in this list:

Oh, well I'll only be 123. A spring chicken.

That is the age I would be if I somehow managed to make it to the next total solar eclipse visible from mainland UK (23rd September 2090). The next total solar eclipse visible from my home town of Ulverston in England is 14th June 2151 (2m34s of totality).

Glad you had the luxury of staying put.  Back in 2017 when we missed going to see totality in Oregon we decided that in 2024 we'd be traveling out to Texas.  We had the foresight to book everything months in advance thus dodging all the price gouging.  Absolutely no regrets, joy only (plus a chance for a little sightseeing in Texas).

Just keep taking the sirtuin activators and you'll be OK.
