The news of October 15, 2023 brought us a spectacular astronomical event: an annular solar eclipse. This rare phenomenon has been observed in the United States as well as in several countries in Central and South America.
During an annular eclipse, the Moon is slightly further from Earth compared to a total solar eclipse, creating a “ring of fire” around the Sun. Millions of people had the chance to admire this celestial spectacle, where the Moon partially covered the Sun, revealing this famous luminous crown.
The event generated great scientific interest from NASA, which was able to study the temperature changes and atmospheric variations caused by the eclipse. Sounding rockets were launched to collect data on magnetic fields, electron density and temperature.
Unfortunately, some places were obstructed by clouds, which prevented optimal observation of the eclipse. However, many countries were able to enjoy this celestial spectacle, from Oregon to southern Texas, including Mexico, Honduras, Costa Rica, Nicaragua and Colombia.
This annular eclipse also served as preparation for a total solar eclipse expected in April 2024 in the United States. These two phenomena will be unique opportunities for scientific research, allowing us to better understand the effects of solar eclipses on our atmosphere and our ionosphere.
In conclusion, the annular solar eclipse of October 15, 2023 offered a fascinating spectacle to American and Latin American observers. This astral event aroused great scientific interest and opened new perspectives for research in the field of astronomy and solar physics.
