Traditionally, thousands have gathered at the Stonehenge site (Great Britain) to celebrate the start of summer. But the summer solstice 2020 will not be quite like the others. If the Earth hasn’t stopped spinning, the coronavirus crisis is still there. This year, for health reasons, the site will be closed to the public.

Surprising information has been circulating online in recent days. We are told that this Friday, July 8, at exactly 1.15pm Paris time, 99% of the world population somewhere will still be the rising and setting of Sun. This July 8, finally like everyone else!

But the information deserves some clarification. First of all, note that in fact, this Friday, July 8, 2022, at 1:15 pm, almost all of the most populated regions of the world will receive their share of the sun. North America, South America, Europe, Africa and much of Asia. Eventually only Australia, New Zealand, parts of Southeast Asia and Antarctica will be immersed in the dark. Regions where only about 80 million people live. This is about 1% of the world population.

Between day and night, twilight

But note all the same that this doesn’t mean 99% of the population will be sunlit. A closer look shows that 83% of us will actually be in broad daylight. The 16% missing to reach the stirring figure will be hit by a light more indirect. They will be immersed in a dusk.

A dusk because there are actually three phases of twilight. The darkest, what scientists call astronomical twilight, feels like night. The brightness which then comes from a sun placed between 12 and 18 ° below the horizon is so weak that it is not perceptibleeye human. And 3% of the world’s population will be in this situation on Friday 8 July at 1.15pm.

People living in regions bathed in so-called nautical twilight – with the sun between 6 and 12 ° below the horizon – will only be able to distinguish with night if they are in non-urban areas. Away from there light pollution city. Finally, people affected by civil twilight will be able to perceive the light of day.
