Hello and welcome to BBC News’ coverage of what’s expected to be a stunning sky spectacular.

A total solar eclipse will be witnessed today on the North American continent.

The Moon is going to pass in front of the Sun to cast a deep, fast-moving shadow across the face of the Earth. And we’re going to be following it all the way – from Mexico in the southwest to Newfoundland, Canada in the northeast.

It’s been dubbed the Great American Eclipse Part II, because of course the US got to experience a similar event in 2017. But this one promises to be even better, not least because many more people are likely to get to see it this time around.

It’s thought some 32 million US citizens will be able simply to step outside their front door to watch day turn to night. Hundreds of thousands more will cluster along the path of the great shadow.

But a word of caution from the off: Never, ever look directly into the Sun without protection. It’s mega dangerous and could seriously damage your eyes. Remember to stay safe.

We’ll remind you how as the day goes on. Right, I think it’s time to party.
