From the Astronomical Treatise (Chapter 22) of the Annals of the Later Han Dynasty:

"In the second year of the reign of the Zhong-ping Emperor, 10th month, day kuei hai, a guest star appeared within the Southern Gate [constellation]. It was as large as half a mat. It showed the five colors and it was happy-angry [it scintillated]. It gradually became smaller and disappeared in the 6th month of the second year after. According to the standard prognostication this means insurrection. When we come to the 6th year, the governer of the Yuan-shou region punished and eliminated the middle officials. WuGuang attacked and killed HeMiao, the general of chariots and cavalry, and several thousand people were killed."
