The 1892–1893 atmospheric-optics literature on unusual solar halos in Egypt

Record summary

Late nineteenth-century Egyptian meteorological and astronomical records contain observations of halos, parhelia, coronae, and other unusual appearances around the Sun. Such records are relevant because later close-encounter narratives sometimes describe luminous discs, mock suns, or structured lights without recognizing atmospheric optics. The existence of the relevant institutional records is plausible through Egyptian observatory and meteorological publications, but individual incidents and dates must be checked. This lead should be pursued as an archival search, not treated as a known unexplained case.
