2019 equinox: 12 facts for the first day of autumn



Find out when the Autumn Equinox happens and what to expect as we say goodbye to summer.

Hello Autumn! Although it happens year after year, the arrival of autumn is always a little surprising. Almost as if on a switch, one day late in the summer you can feel it – a fine crispness in the air. And before you know it, it's pumpkin spice – everything everywhere. Suddenly we weave in sweaters and wear boots and are bombarded with orange shades, often even before the thermometer guarantees it. After defining it in the long hot August, it's exciting.

We can thank the autumn equinox for this transition from a hot summer to a cozy autumn. And while most of us are aware of when the first day of fall lands on the calendar, there is more to the equinox than the view. Consider the following

1
. When is the equinox in 2019?

This year, the autumn equinox arrives at exactly 07:50 UTC (3:50 AM EDT) on Monday, September 23. Unlike a New Year's Eve event that follows the clock around time zones, equinoxes occur at the same moment everywhere.

2. It's autumn, it's spring!

Two equinoxes are held annually, autumn and autumn, which marks the beginning of spring and autumn. They are the opposite of the northern and southern hemispheres – so for those of you in the south, happy spring!

3. It's all about the celestial equator

The autumnal equinox occurs when the sun crosses the celestial equator, which is an imaginary line of the sky corresponding to the equator of the earth. (The Old Farmer's Almanac describes it as a plane of the Earth's equator projected on a sphere.) Every year, this happens on September 22, 23, or 24 in the Northern Hemisphere.

4. The leap year plays a role

Because on Earth it takes about 365.25 days to orbit the sun – and why we have a leap year every 4 years – the exact equinox time varies from year to year, usually this happens about six hours later in the coming years . In leap years, the date jumps back all day.

5. Gives us longer nights

From here, the nights are longer than the days, and the days continue to shorten until December, when the light begins to slowly climb back to the long summer days. Winter solstice is technically the shortest day of the year, while summer solstice in June boasts the most sunshine. 6. The Meaning of "Equinox"

"Equinox" comes from the Latin words "equi" meaning "equal" and "nox" meaning "night". This means that there will be equal amounts of daylight and darkness, but this is not true.

7. The equinox is not exactly equal

This year the sun will rise at 6:44 AM EDT and set at 18:51, giving us ~ 7 minutes a day at night. Although the sun is perfect above the equator, we mark sunrises and sunsets in the first and last minute the top of the disc appears. In addition, due to the refraction of the atmosphere, the light bends, making it as if the sun rises or sets earlier.

8. What is Equilux ?

Despite the name of the equinox, the same day and night does not occur until sunrise and sunset are exactly 12 o'clock, which depends on the latitude of the location; the closer to the equator, the closer it is to the equinox. This day is known as the equinox – from the Latin "equi" to "equal" and "lux" to "light".

9. Sun Signs Also Play Together

For astrology lovers, the morning of the autumn equinox is when the sun goes down to Virgo and enters Libra; scale, how appropriate! According to astrologers, this is an opportune moment for balance and harmony.

10. It determines the harvest Moon

As for the other celestial globe we obsess over, the full moon closest to the autumnal equinox is called the Harvest Moon for Luminosity, which enables farmers to work late. Also called the Full Corn Moon (see: Full Moon Names and What They Mean). Moon harvesting is usually associated with the full moon in September, though if October's full moon happens to fall closer to the date, it takes the title. This year's Harvest Moon happened on Friday, September 13th.

11. The northern lights will be further visible

With more darkness at night, there are simply more hours to watch; if you are close to the Arctic Circle in the summer, there is too much daylight. But the aurora is also stronger around the equinox due to the planet's 23.5 ° slope and the magnetic field of the solar wind … a magic combination that

12. The perfect moment is to get your bearings

And this year of equinoxes, as it happens every year, the sun will rise just for the sake of the East, and it will set just to the west. Everywhere on Earth, except for the North and South Poles, there are straight east and west lengths on the horizon; By watching the sun travel this route on September 23, no matter where you are, you can see where you are pointing it for your location. Choose a landmark, make a thoughtful note, and enjoy the knowledge that while so much of this world is in flux, the sun is constant and will return to its perfect East and West in the days of equinox.
