Abstract: The results of observations of the two SNRs HB 9 and IC 443 are discussed. A map of HB 9 is presented whose main features are an elongation in the northerly direction and a strong region at the center of the map. The integrated flux density is 750 + or - 150 Jy at 34.5 MHz, and the spectral index is found to be constant in the range 34.5 to 2700 MHz. The shell structure of IC 443 was unresolved, and the integrated flux density is 440 + or - 88 Jy at 34.5 MHz. The spectral index in the frequency range from 20 to 10,700 MHz is -0.46 + or - 0.04.
