Abstract:

VLF emissions between 3.9 and 10.4 kHz are observed at high altitudes in the slot region L approximately 2.5 to 3.6 by a receiver aboard spacecraft OV1-14 1968-26B. The maximum spectral intensities of 1.1 microgammaHz to the 12 power and 2.8 microvoltHz to the 12 power on the magnetic and electric antennas, respectively, occur in the 5.6-kHz channel. The waves can resonantly interact with energetic electrons above approximately 50 keV at L 2.5, and the measured wave intensities are ample to account for the observed lifetimes of medium energy electrons in the slot region.
