Scientific paper

The radio emission flux density of Cassiopeia A relative to Cygnus A was measured with the DKR-1000 radio telescope in 1987, 1988, and 1991. The mean rate of the secular flux-density decline at the 7.9-m wavelength during 1956-1991 is determined, on the basis of earlier published data, to be 0.70 +/- 0.19 percent/yr. This value is half that extrapolated to the 38-MHz frequency, which was obtained from frequency dependences of the secular decrease rate for Cassiopeia A radio emission.
