ringförmige

Ringförmige, also known as annular eclipses, are a specific type of solar eclipse where the Moon covers the Sun's center, leaving the Sun's visible outer edges to form a bright ring, or annulus, around the Moon. This phenomenon occurs when the Moon is at or near its apogee, the farthest point from Earth in its elliptical orbit, and thus appears smaller than the Sun in the sky. The result is a "ring of fire" effect, where the Sun's corona is not visible to the naked eye.

Annular eclipses are different from total solar eclipses, where the Moon completely covers the Sun, and from partial eclipses, where only a part of the Sun is obscured. The path of an annular eclipse, known as the antumbra, is much smaller than that of a total eclipse, typically only a few hundred kilometers wide. Observers within this path see the annular phase, while those just outside it may experience a partial eclipse.

Ringförmige eclipses are relatively rare and can only occur when the Moon is in its new phase. They are a fascinating astronomical event that offers a unique opportunity to study the Sun's corona and other solar phenomena. However, they also pose a risk to observers, as looking directly at the Sun during an annular eclipse can cause permanent eye damage. Specialized solar filters or indirect viewing methods are recommended for safe observation.
