What is a Sun Hybrid Eclipse?
SOLAR ECLIPSE
An eclipse of the Sun occurs when the Moon passes between the Earth and the Sun. Because of this, the Moon hides the Sun and casts a shadow on the Earth, which can be seen from a very small sector somewhere on the globe.
The different visualizations that can be had of a solar eclipse are due to the angle with which the solar rays affect the Moon, which in turn also influences the type of shadow projected towards different places on Earth.
The 3 most common types of solar eclipse are: Total, Partial and Annular; however there is a fourth less frequent type called Hybrid Eclipse.
HYBRID ECLIPSE
This phenomenon is very special and corresponds to a combination of Total and Annular eclipse. From some regions of the Earth this type of eclipse adopts the appearance of an annular eclipse, while in others it will appear as a Total eclipse.
Hybrid eclipses occur when the moon is at a specific distance from Earth, close enough to project its umbra (shadow) over some regions of the globe, but far enough also to make that umbra not appear in other regions. regions.
The hybrid eclipse begins and ends with the appearance of an Annular eclipse, but for a time and for observers within the umbra, it will appear as a Total eclipse. Hybrid eclipses account for about 5 percent of all solar eclipses that occur.
Solar Hybrid Eclipse April 2005
Fred Espenak it was at the center of the shadow route of the Moon, about 2200 kilometers west of the Galapagos Islands; for him the eclipse was total; the silhouette of the Moon covering exactly the bright solar disk for a few moments. With his camera he took a picture of the whole, revealing the extensive solar corona and the prominences rising above the edge of the Sun.
On the other hand, Stephan Heinsius, from the Penonome Airport in Panama, the apparent size of the Moon had diminished enough to create an annular eclipse, showing a full crown of the Sun's brilliant disk in the form of a ring of fire.
The photographs obtained at the two sites are compared in the previous image, which was APOD on May 6, 2005.
TOTAL ECLIPSE
During a total eclipse, the moon completely blocks the sun's visibility. These eclipses occur when the moon is close enough to project its umbra over some regions of the Earth. What the observers outside these regions will have before their eyes will be a partial eclipse. During a total eclipse the corona can be observed, the outermost and warmest layer of the solar atmosphere.

ECLIPSE CANCEL
During an annular eclipse, the moon covers the center of the sun, leaving a ring or solar ring visible around the moon. These eclipses occur when the moon is farthest from the Earth and located just in front of the sun. Due to the distance, the umbra of the moon (the zone of completely dark shadow) is not long enough to reach the Earth. The zone of our planet where the annular eclipses are visible, that is, where the body of the moon apparently contained within the sun can be observed, is called antumbra. Observers outside this area will simply see a partial eclipse.

PARTIAL ECLIPSE
As its name implies, a partial solar eclipse is one in which only a portion of the sun's rays are blocked by the moon. The partial eclipse occurs when the penumbra, (partially shaded region of the moon's shadow), is projected onto some parts of the Earth. During a partial eclipse some observers will see a sun almost covered, while others located in different parts of the world will observe a "rising" sun. Partial eclipses can occur alone or as part of an annular or total eclipse.
