A survey of the galactic background radiation at 3.93 and 6.55 MHz is presented for the region between declinations of -60' and + 60 . The observations were obtained with the 229-m travelling-wave V-antenna on the Radio Astronomy Explorer- 1 satellite with an angular resolution of the order of one steradian. The results are consistent with the findings of high-resolution ground-based surveys at low frequencies and provide a first step in extending such observations over the whole sky.
