What is the Fall Equinox 2022 and when does it come?

On September 23, at 3:04 a.m., Spanish peninsular time, the Earth will be at a point in its orbit around the Sun that marks the beginning of a new season, fall. The autumnal equinox will then take place, the only day of the year along with spring in which the Sun rises in the east and sets in the west on the entire planet.

It is the explanation of the Astronomical Association of Huescawhich has organized special activities to observe the event and cites the calculations made by the National Astronomical Observatory (National Geographic Institute-Ministry of Development). The season will last approximately 89 days and 21 hours, and will end on December 21 giving way to the winter solstice.

“Furthermore, as also happens in spring, the length of the day (in solar hours) and that of Friday night will be approximately the same: twelve hours. The new season begins when the Sun is located in the plane of the terrestrial equator. When this happens, the length of day and night practically coincidewhich is why it is also known as the autumnal equinox,” says the association.

According to the Group, the sky after sunset in early fall will have Jupiter and Saturn as the only visible planets. From December they will make their appearance in the sky Mars to the east and Venus and Mercury to the westso the season will end with five planets visible at nightfall.

During the 89 days that the season lasts, There will be two eclipses, one of the Sun and the other of the Moon.. The solar eclipse will happen on October 25 and will be partial. In Spain, it will be visible in the peninsular northeast and the Balearic Islands, but with very low magnitudes. The lunar eclipse will take place on November 8, it will be of a total type and will not be seen in Spain.

And with autumn comes the time change. It will take place on the last Sunday of October (the 30th), when at three in the morning we will have to turn back the clock until two o’clockand thus the winter time will be recovered, so that day will officially have one more hour.

The Astronomical Group invites you to go on Friday, September 23, at 7:30 p.m. to the Parque de las Mártires de la Libertad (on the hill opposite the hermitage of the Mártires) to welcome autumn. The activity will not only take place in the capital. In Sarinena It will be hand in hand with AstroMonegros, next to the Laguna observatory.

For those interested there will be an observation of the sunset of the equinox, if the weather allows it. The Sun sets this day in Huesca at 7:58 p.m., exactly due west, something that only happens on this date and on the spring equinox.

Telescope observations may be made, provided the weather conditions are suitable. Jupiter and four of its visible moons (Europa, Ganymede, Io and Callisto) will be visible; Saturn with its moons (Titan and Rhea); and the International Space Station with two passes, at 20:31 and 22:09, just what it costs to go around the Earth.
