Another total solar eclipse is coming to North America, this time on April 8 2024.

Beginning in Mexico and passing across the US and Atlantic Canada, it’s estimated that 32 million people live inside the path of totality for the 2024 total solar eclipse.

That’s 20 million more than in 2017 during the last total solar eclipse in the US, which went coast to coast.

This time it’s also much longer, with totality peaking at 4 minutes and 27 seconds. It comes less than six months after the October 14 ‘ring of fire’ annular solar eclipse in the US, Central and South America.

What is a total solar eclipse?

A total solar eclipse occurs when the Moon’s apparent size in the sky is exactly right to completely cover the Sun’s disk, making it possible to glimpse the solar corona around the Moon’s silhouette for a few minutes.

This is called totality, during which the sky turns a deep twilight.

On either side of totality, it’s possible to see phenomena such as Baily’s beads and diamond rings as the last and first drops of sunlight are visible.

The path of totality for the April 8 2024 total solar eclipse will be around 120 miles/190 kilometres wide.

Places from where the April 8 solar eclipse will be visible include:

Mexico

USA

Canada

Parts of the Texas Hill Country that will experience totality on April 8 2024 will have seen the ‘ring of fire’ annular solar eclipse on October 14 2023.

Observing totality

The closer you stand to the centre of the path of totality during a total solar eclipse, the longer the duration of totality

But you also have to think about weather.

The further southwest you are the better chance for clear skies.

Mexico, which will see its first total solar eclipse since July 11, 1991, is where the chances of a clear sky are highest.

Totality for the 8 April solar eclipse will be seen first in Mazatlán on the Pacific coast (4 min 17 sec, 11:09 am MST) and the Moon’s central shadow will leave the planet at South Bird Island, Newfoundland (2 min 53 sec, 5:13 pm NDT) in Canada.

Iconic sites where totality will be visible include:

How to observe an eclipse safely

You should never look directly at the Sun without proper eye protection (in the form of eclipse glasses and solar filters) and some phases of this solar eclipse will be too dangerous to look at with the naked eye.

Everyone across North America will need to wear eclipse glasses or use solar filters to safely view all or parts of this event.

For those outside the path of totality, eclipse glasses will be required for the entire event.

For those inside the path of totality, the few minutes of totality is perfectly safe to look at with the naked eye (that is the attraction of the event), but it’s preceded and followed by a long partial solar eclipse that requires eclipse glasses, so you should always observe with caution.

As is always the case with any form of solar observing, if you are not sure what you’re doing, don’t attempt it.

A safer way is to observe the eclipse indirectly, by making a solar projection screen.

The same safety warnings apply to cameras and binoculars, which should be used only with solar filters during the partial phases.

You’ll need to remove the solar filters during totality if you want to capture the corona on camera.

But keep an eye on the time so you know when the Sun is about to remerge – it’s very important to replace your filters before then if you don’t want to damage your camera.

You could also observe the April 8 eclipse close-up by using a solar telescope.
