A Revisit to the Guest Star of A.D. 185

The guest star of A.D. 185 is possibly the earliest recorded supernova, and the radio source RCW 86 is believed to be its remnant. However, a restudy of ancient Chinese literature suggests that RCW 86 is unrelated to the guest star, which probably had a visible duration of only 7 months and appeared between beta and dgr Centauri, instead of the previously proposed 20-mtonth duration and a location between agr and ,beta Centauri.
