Exploring the grandeur of the Autumn Equinox at its peak.
The autumnal equinox, a significant astronomical event, is set to occur on Monday, September 22, 2021. This global phenomenon marks the beginning of a new season in the northern hemisphere, ushering in autumn.
In the northern hemisphere, the autumnal equinox spans from the end of September until the end of December. During this period, day and night are almost equal in length, a unique characteristic of this event. Contrastingly, in the southern hemisphere, the autumnal equinox occurs on opposite dates, from the end of March until mid-June.
The autumnal equinox is not associated with eclipses or supermoons, contrary to some misconceptions. However, observing the shadow cast by the movement of the Sun can help one witness this event. At noon during the autumnal equinox, the shadow generated will be the smallest possible.
Observers can track the autumnal equinox by following the shadow of a pole or any vertical rod that projects a shadow, like a sundial. The angle the shadow has with respect to the pole will be the latitude of that point on Earth.
The autumnal equinox is of great significance for sowing and crops, as it signals the optimal time for planting certain crops in many countries. In Mexico, the autumnal equinox will take place on Monday, September 22, at 12:20 pm local time.
This event is not limited to specific sites like Chichen Itza or Teotihuacan. While these places in Mexico offer a magical view of the autumnal equinox due to their location and architecture, the event can be observed at various locations around the world.
The exact date and time of the astronomical autumnal equinox in 2021 will be on September 22, 2021, when the sun crosses the celestial equator moving southward, marking the start of autumn in the northern hemisphere. The autumnal equinox occurs when the Sun is directly over the Earth's equator.
The autumnal equinox is an astronomical phenomenon that occurs annually on Earth, reminding us of the Earth's tilt and the changing seasons. So, mark your calendars and prepare to witness this natural wonder on Monday, September 22, at 18:20 GMT in the northern hemisphere.
