Scientific paper

Results are presented for measurements of absolute effective sky temperatures at frequencies of 79 and 115 MHz, which were made with an angular resolution of 5.4 by 9 deg along declination 50 deg 30 min for right ascensions between 2 and 22 hr. The effect of radiowave absorption and thermal emission by the interstellar medium on the magnitude of measured angular variations in the total cosmic radio spectrum is examined. The mean value of the spectral index for nonthermal galactic radio sources is found to vary from 2.48 to 2.52 along declination 50 deg 30 min, except in directions toward the local radio arm, where the index may decrease to its lowest values. It is noted that the spectral index decreases as right ascension increases from 17 hr to 20 hr, where the beam trajectory approaches a spur of Loop III.
