Abstract

We present a survey of the 45 MHz radio continuum emission in the declination range +5° to +65°. The observations were made with the circular filled array of the Japanese Midle and Upper Atmosphere Radar with a half-power beam width of $3{{\rlap.}{^{\circ}}}6$ . The results are presented in sets of maps in galactic and equatorial coordinates (Epoch 1950).

Key words: radio continuum: ISM / surveys / galaxy: structure
