AbstractWe have continued our program to measure the long-wavelength spectrum of the cosmic background radiation. Our previous observations were at five wavelengths . 0.33, 0.9, 3.0, 6.3, and 12.0 . and had a weighted average value of 2.73{+ or -}0.05 K and deviated from a Planckian spectrum by less than 6%. In August 1984, we repeated our observations at 3.0, 0.9, and 0.33 cm and made new observations with a radiometer tunable from 1.7 to 15 cm. Preliminary analysis indicate that the new data are consistent with our previous results.
