1 Don't Look With Naked Eyes
Take a photo. But don't look at the eclipse. I remember this advice from last time. I know to wear sunglasses in sunny weather, even when not looking directly at the sun. I once read it can cause or accelerate cataracts in older people. I know you are supposed to wear goggles when skiing even on overcase days to prevent snow blindness.
You can buy special glasses online, if you have time. Or attend an event where you see a projection. Or make up a pinhole camera device, which is either difficult or dangerous in my view.
However, US TV channel Fox news has been running demonstrations of making a viewer from a cereal box. One important thing is to stand with the sun behind you.
2 Don't drive
The sudden plunge into darkness can cause accidents.
UK
Cities in the north of England are in luck. Fortunately, for risk aversion types like me, London does not get a view, only the north of England Although there are annual partial eclipses, a full moon eclipse won't be in the UK for another 60 or so years. Although I was hoping to live beyond a hundred years of age, that timing is rather challenging for me.
My late father was an optitican. But he is not here for me to ask. I went to Wikpedia. As usual, I found an enormous amount of highly technical information. But lots of links to sources, plus useful and engaging articles on related subjects.
I could try Simple Wikipedia, but I got sidetracked by the number of solar eclipses, and moon eclipses, full partial eclipses, partial eclipses, even triple eeclipses or ratter two items hidden behind a third. If you miss this one, there will be another.
USA & Mexico
The eclipse is appearing in a line down the USA and Mexico. We have friends in the UK who went to Mexico especially to see the eclipse.
Debate
We were debating hether the eclipse is always in the day, or night, or sunset.
'You don't see the sun at night. So it can't be at night.'
' But what about countries which have midnight sun?'
Types of Eclipse
Basically, an eclipse is a bigger object hiding a smaller one. It happens all over the universe as everything moves around. You can have solar exlipses, lunar eclipses, whole eclipses and partial eclipses. Eclipses of moons and planets, all sorts of things.
The Word Eclipse
The word eclipse comes from the Greek, like so many scientific terms. The metaphor to eclipse somebody is related. If I stand in front of somebody smller on a stage, I am eclipsing them. If my win in a speech contest gets more publicity than somebody else's entry, my win eclipses theirs. (Or vice versa.)
I now have more questions than answers about solar eclipses. But I know more now than I did before.
In olden times people feared it was the end of the world.Now we know it isn't.
Animals in zoos are spooked out. Then go silent.
USA
I was on my computer watching on the large screen live from Fox.
The commentator said that in Mexico people were clapping, cheering and crying. Next stop was Texas.
