Abstract : The direction of the Poynting flux, up or down the geomagnetic field, has been determined for several types of very-low-frequency (30 Hz to 10 kHz) radio noise phenomena observed with the Injun 5 satellite, thereby providing information about the source region of these waves and their propagation in the magnetosphere. Determinations of the Poynting flux direction of short-fractional-hop whistlers and proton whistlers show that they are propagating up the geomagnetic field in accordance with the accepted theories of these phenomena, thereby providing a good check on the experimental technique. Measurements are presented on the Poynting flux direction of subprotonospheric whistlers, periodic emissions, ELF hiss, chorus, VLF hiss, and a new type of emission called a saucer. (Author)
