A new supernova remnant RX J1713.7-3946 in the constellation Scorpius is suggested to be the remnant of the AD393 guest star. The available historical records of the AD393 guest star are introduced in this letter. According to the ROSAT observation of RX J1713.7-3946 and the historical records of the AD393 guest star, the visual position, distance, and age of both RX J1713.7-3946 and the AD393 guest star are in agreement.

Key words: history and philosophy of astronomy – stars: supernovae: individual: AD393 – ISM: supernova remnants
