The emperor of Japan and the aurora



On October 3, 1985, I gave a special lecture on the aurora for the Emperor of Japan in his palace in Tokyo. It seems the Emperor, a marine biologist, has an unusual interest in the aurora. After my slide presentation, he asked how we confirm ancient sighting reports of the aurora in Japan. He was not satisfied with my response that anomalous events in the sky were well documented in an ancient publication entitled Japanese Meteorological Data and asked further how one could confirm such sightings as auroral events. He was visibly pleased to learn that the dates of these sightings coincided with those recorded elsewhere in the world.
