September 29 will be the autumn equinox, one of the six most important astronomical phenomena that stars the sun every year, with the particularity that that day lasts the same as the night.
The phenomenon will be recorded about six days after the formal start of autumn and the end of summer this year scheduled for next 23 this month at 02:51, as astronomer Eddie Salazar Gamboa informed Notimex.
The academic recalled that two equinoxes are registered a year, when the day lasts the same as the night and these occur in the spring and autumn, two solstices and two suns at the zenith.
On the 29th, the sun will rise at 06:48 hours and will set at 18:48 hours, that is, the night and day will last exactly the same time and hence the name of equinox is derived.
He indicated that there is evidence that the phenomenon was of great importance to the ancient Maya, as well as other great civilizations such as the Egyptian, as it indicates until today that the rainy season is about to end and the harvest of the crops must begin.
Similarly, as with the spring equinox in Chichen Itza, the phenomenon of light and shadow is known as “the descent of Kukulkan”, but unlike the spring, here the triangles generate the effect of descent and ascent, he said.
It is also possible to see the passage of the Sun through the so-called Temple of the Seven Dolls in the archaeological zone of Dzibilchaltún, located just 17 kilometers north of this capital.
These phenomena could begin to be observed six days before the formal start of autumn and up to six days after the equinox.
In that sense, the Board of Trustees of the Cultural and Tourist Services Units of Yucatán (Culture) announced that from next day 21 it will deploy a logistics and security operation in Chichén and Dzibilchaltún, as a greater influx to those sites is expected Pre-Hispanic to observe the phenomena.
