Abstract
A high-resolution radio map of Kepler's SNR has been constructed from 5 GHz observations made at Cambridge and at Owens Valley. The remnant is shown to have an irregular shell structure of 170” arc diameter, which is brightest in the north, with a gap at the south and a peculiar dent to the east. The patches of diffuse emission that comprise the optical remnant are largely concentrated in the brightest parts, but they are expanding much more slowly than the average shell velocity. The remnant has a close resemblance to Tycho's SNR, but is rather more irregular.Keywords
