Popis: The comet 27 P/Crommelin was discovered in 1457 and since then observed six times up to 1956, so its average period is 27.79 years. According to Korean ancient annals, however, comet 27 P/Crommelin was first observed in B.C. 44 and was observed 16 times up to 1457. We traced the records with a period of about 28 years, compiled a list of them and showed that all those records are concerned with the comet 27 P/Crommelin. According to extrapolation of the brightness, the comet 27 P/Crommelin might be one of the brightest comets observed in human history, so ancient people could easily observe this comet with the naked eye. We examined the parallel records in Chinese history and concluded that the Korean historians might have added more detail to their reports by referring to Chinese records.
