He annular solar eclipse which will take place next Saturday October 14th All Mexicans have great expectations about it, as it is a rare astronomical event that cannot always be observed in the country.
Although they are rare, several solar and annular eclipses have been observed in Mexico and here we tell you about some of the most spectacular.
Annular solar eclipse of November 22, 1919
On this date a annular solar eclipse which, however, could only be partially observed in Mexico. This started at 5:45am and ended at 7:59am. In our country, the solar eclipse was partial and, according to the data at that time, it began in the capital at 5:45:42 and ended at 7:59:36.
The eclipse was partially visible in various parts of the United States and in some South American countries such as Haiti, Venezuela, the Dominican Republic, Barbados and Brazil, but its greatest visibility and where the famous “Ring of Fire” was seen was in some countries of the African continent. According to NASA, this was the longest solar eclipse since January 5, 1647.
Annular solar eclipse of April 7, 1940
An annular solar eclipse was observed in the northern region of the country. This solar eclipse was part of what scientists call the Saros 128 solar cycle, which includes a total of 73 eclipses, the peculiarity of which is that they occur at regular intervals of 18 years and 11 days. The series of these eclipses began with a partial solar eclipse on August 29, 984 AD
Eclipses of the 1960s
The decade of the 1960s was privileged in this respect astronomical eventssince a total of 5 solar eclipses could be observed in these 10 years, albeit partial.
These eclipses occurred on the following dates: September 29, 1960, July 20, 1963, May 30, 1965, November 12, 1968, and September 11, 1969.

Without a doubt, two of the most significant solar eclipses in the country are those of March 7, 1970 and July 11, 1991. Here we explain why.
Total solar eclipse of March 7, 1970
During this decade, Mexico was the headquarters of one of the astronomical events the most important of the century, because on March 7, 1970 a total solar eclipse whose point of greatest visibility was the state of Oaxaca.
The phenomenon occurred in the Isthmus of Tehuantepec and was particularly visible in the city of Miahuatlán, which was named after the phenomenon for many years “Science Capital of the World”.
This name was given to it because on this day many new astronomical devices were tested for the first time and because many scientists from all over the world gathered in this small town to observe the unique phenomenon.
Total solar eclipse of July 11, 1991
Finally, on Thursday, July 11, 1991, another one of the most remembered solar eclipses in the country occurred as it was visible in 20 states across the country.
The event, which began at 11:47 a.m. in La Paz, Baja California, and ended at 1:46 p.m. in Chiapas, made it seem like night in broad daylight for a few minutes.
This phenomenon is classified as one of the total eclipses The solar exposure lasted longer than those recorded, as its peak lasted a total of 7 minutes, while the average duration is only a few minutes and even seconds.
The eclipse caused drastic temperature fluctuations, dropping from 31 to 6 degrees in Baja California Sur due to the darkening caused by the solar cover.
Other partial eclipses observed in Mexico, albeit of a smaller magnitude, were those of June 11, 2002, May 20, 2012, and October 23, 2014.
