Scientific paper

Observations of 2-arcmin resolution of the 1.4-GHz continuum emission from DA 530 (l = 93.3 deg, b = 6.9 deg) are described. The brightness distribution and the nonthermal spectrum are characteristic of a supernova remnant. The mean surface brightness of the SNR implies a diameter of 47 (+ or - 15) pc and a distance from the sun of 6.9 (+ or - 2.2) kpc. Within a factor of two, the age of DA 530 is estimated to be 3000 years.
