Abstract

This paper presents high resolution radio observations of the relatively bright supernova remnant G11.2–0.3 made with the VLA. These reveal a clumpy shell of emission which resembles an evolved version of Cassiopeia A, thus strengthening the case for association of this remnant with the supernova of AD 386.
