What are 5 facts about autumnal equinox?
The autumnal equinox is one of the most important events in the year, signifying the transition from summer to fall. It occurs twice every year and marks the moment when the sun crosses the equator, making day and night of equal length. Here are 5 facts about the autumnal equinox you should know.
Equinox is an instantaneous phenomenon
The autumnal equinox is an instantaneous phenomenon that lasts for only a few seconds. It is the exact moment when the sun crosses the celestial equator and the day and night are of equal length all over the world. This phenomenon is referred to as the ‘equal night’, ‘autumnal equinox’ or the ‘autumn season’.
Day and Night are not precisely 12 hours each
Though the total length of day and night is equal, the actual hours of daylight and darkness may be slightly different. This is because the sun’s rays are spread out over a larger area in the atmosphere, which affects the amount of light received. In addition, the Earth’s curvature and atmospheric refraction can also cause the actual hours of day and night to be slightly different.
Equinox does not occur on a fixed day
The autumnal equinox does not occur on a fixed day every year. It usually happens on the 22nd or 23rd of September, but this can vary from year to year due to the Earth’s orbital variations. In fact, the autumnal equinox can happen up to a week before or after this date.
Equinoxes signal the start of Northern Lights
The autumnal equinox is the start of the aurora borealis season in the Northern Hemisphere. This is when the Northern Lights can be seen in the sky. The Northern Lights are a natural light show created by the interaction between the Earth’s magnetic field and the solar wind.
Harvest Moon in the Autumnal Equinox
The Harvest Moon is the full moon that occurs closest to the autumnal equinox. This full moon is particularly bright and orange in color, and is a sign of the upcoming harvest season. The Harvest Moon is an important event for many cultures and is celebrated with festivals and other special ceremonies.
In conclusion, the autumnal equinox is an important event that marks the transition from summer to fall. It is an instantaneous phenomenon that signifies the moment when day and night are of equal length. While the actual hours of day and night may be slightly different due to atmospheric conditions, the equinox does not occur on a fixed day every year. Additionally, the equinox signals the start of the aurora borealis season and the Harvest Moon.
