In the consulship of Gnaeus Octavius

In the consulship of Gnaeus Octavius and Gaius Scribonius a spark was seen to fall from a star and increase in size as it approached the earth, and after becoming as large as the moon it diffused a sort of cloudy daylight, and then returning to the sky changed into a torch; this is the only record of this occurring. It was seen by the proconsul Silanus and his suite.
