Radio continuum observations at 1420 MHz of the new SNR G65.2+5.7 in Cygnus.
Abstract
Radio continuum observations at 1420 MHz of the optical SNR discovered by Gull et al. (1977) are presented. Intense radio ridges appear to coincide with bright optical filaments. Observed and derived parameters are tabulated. The main characteristics of this SNR are: diameter of about 75 pc, distance of approximately 0.9 kpc, expansion velocity of at least 50 km/s, age of no more than about 240,000 yr, and total kinetic energy of around 13 x 10 to the 51st erg. A short comparison with other SNRs is made.
