Mexico, Mar. 19 (Notimex).- Only two days a year, during the equinoxes of spring and autumn, it is possible to enjoy the same number of hours of light as of darkness, and during this event the Sun rises exactly on the east to hide right on the west.
Although the same astronomical phenomena occur in both equinoxes, the one of spring has the most symbolism, since it refers to a balance between light and shadow.
In an interview with Notimex, Luis Enrique Erro Planetarium astronomer, Wilder Chicana Nuncebay, recalled that this phenomenon will take place on March 20 at 3:58 p.m.
"It is the moment in which the Sun crosses the equator from south to north in its apparent motion in the sky," he said.
He added that only on the days that mark the beginning of spring and autumn the "star king" rises on the east to set in the west.
Chicana Nuncebay explained that while in the northern hemisphere the arrival of spring is celebrated, in the southern cone they receive the entrance of autumn.
Hours after the arrival of spring, the last of the three supermoons of 2019will make its appearance in the night sky, an event that is characterized because the Moon is in its full phase and at a minimum distance from Earth.
"Do not expect to see a huge moon, the apparent diameter grows more or less 10 percent and the total brightness can reach up to 15 percent," said the astronomer.
The full Moon of March 21, 2019 will be the first of four full moons between the spring equinox and the June solstice. It is a relevant event, because most of the time it only houses three moons in this phase.
The last time a supermoon match was presented with the spring equinox was in March 2000, 19 years ago. This event will occur again until March 2030.
