During an eclipse, there are different types of shadows that can be observed. Here are some of the phenomena related to eclipse shadows:

• Crescent Shadows: As a total solar eclipse approaches totality, the sun becomes a thin crescent in appearance, and shadows become much sharper and more detailed. Little crescent shadows start to appear on the floor, and anything that can cast a shadow while allowing small amounts of light to pass through will create these crescent-shaped shadows.

• Shadow Bands: Shadow bands are thin, wavy lines of alternating light and dark that can be seen moving and undulating in parallel on plain-colored surfaces immediately before and after a total solar eclipse. They are caused by the refraction by Earths atmospheric turbulence of the solar crescent as it thins to a narrow slit, which increasingly collimates the light reaching Earth in the minute just before and after totality. The shadows detailed structure is due to random patterns of fine air turbulence that refract the collimated sunlight arriving from the narrow eclipse crescent.

• Umbra, Penumbra, and Antumbra: The Earth and the Moon cast three different shadows causing different types of solar and lunar eclipses. The umbra is the shadows dark center portion, while the penumbra and the antumbra are different types of half-shadows. The type of eclipse we experience depends on the type of shadow that is involved.

In summary, eclipse shadows are the different types of shadows that can be observed during an eclipse, including crescent shadows, shadow bands, and the umbra, penumbra, and antumbra.
