trawiadolion

Trawiadolion is a lesser-known celestial event that occurs during the astronomical phenomenon of a lunar eclipse. It involves the alignment of the Earth, Moon, and Sun, which can cause the Earth to cast a shadow on the Moon's surface. However, in rare instances, this shadow can create a pattern of stripes or bands on the Moon's surface, due to the Earth's irregular shape and the atmospheric conditions in the Earth's polar regions.

The resulting strips of shadow can create a unique appearance, with areas of varying density and contrast. Some researchers have reported that the resulting image can be seen as a swirling, 3D-like effect, with patches of darkness and illumination that resemble a high-finish photographic negative. The periodic variations in brightness and shadow can create a dynamic effect, as the lunar surface seems to shift and change over the course of the event.

The term "trawiadolion" is derived from the Ancient Greek words "trawia" meaning shadow, and "dolion" meaning limit or boundary. It is not a scientific term and has not been widely used in academia. Nevertheless, the appearance of the Moon during a lunar eclipse, with its distinctive bands of shadow and light, has captivated many observers and inspired investigations into the phenomenon.

While its inclusion as a specific celestial event in various catalogs is not well supported, the occurrence of this resulting pattern has been observed by many observers using telescopes and photography, generating several images which help to demonstrate its occurrence alongside of the lunar eclipse.
