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 microgamma/(Hz to the 1/2 power) and 2.8 microvolt/(Hz to the 1/2 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.
