Sun dogs play a small role in the excellent alternative history / horror series “The Terror”, starring two of my favorite character actors Jared Harris and Ciarán Hinds, about the loss of the 1845 Franklin expedition to the Arctic. Thoroughly recommended!
Sigh, yet another homonym: 幻日(genjitsu).
If you try say this in Japan, nobody will know what you're talking about because "genjitsu" (現実) is an extremely common word that means "reality".
