Day and night are equal, the autumnal equinox is coming in a few minutes
Today at 20:19 PM the autumn equinox will occur.
The sun will be high above the equator, and the hours of daylight and darkness will be equal across the world, marking the arrival of autumn in the Northern Hemisphere and spring in the Southern Hemisphere.
Saturn will "greet" the phenomenon, visible under optimal conditions. The planet is at its closest point to Earth, writes ANSA.
This means that the Earth is aligned between the Sun and Saturn, which therefore appears mostly bright.
The equinox occurs when the Sun reaches its highest point at the equator and its rays fall perpendicular to the Earth's axis of rotation.
At that moment, everywhere on the planet, day and night are equal.
Since the length of the solar year does not correspond exactly to the time it takes the Earth to complete one orbit around the Sun, the autumnal equinox is not on the same day every year, but varies between September 21 and 24.
Given the Sun's mostly active period, intense aurora borealis is expected to occur at high latitudes - due to the so-called "Russel-McPherron" effect, ATSH reports.
Finally, considering the mainly active period in which the Sun is currently located, intense aurora borealis are expected to occur – at high latitudes due to the so-called 'Russel-McPherron' effect.
The Russell-McPherron effect predicts that around the equinox, the geometry of the Earth's magnetic field may change, allowing charged particles from the Sun to enter more easily.
