Abstract

The low latitude (b = 2.8°) radio source CTB80 (ret. 1) is a probable, albeit unusual, supernova remnant2 (SNR). A compact high brightness region with a very flat spectrum dominates its centre, and we find optical emission associated with this feature. Here we discuss evidence that CTB80 may be young, and in particular the possibility that it was observed in China at the beginning of the fifteenth century.
