The 1882 Greenwich Observatory Transit Object

Record summary

A nineteenth-century observation associated with the Greenwich Observatory is sometimes cited in UFO histories as an unexplained object or luminous phenomenon recorded by astronomers. It is potentially valuable for comparing professional astronomical observation with later anomalous interpretation and for examining how archival fragments become “UFO cases.” The original context may involve an observation of a conventional astronomical or atmospheric phenomenon rather than a structured encounter. Researchers should locate the observatory’s published records and contemporary astronomical notices before accepting the later UFO label or the commonly repeated date.
