Description
Summary:Positive results pertaining to the triggering of electron precipitation by natural VLF signals suggest that artificial stimulation, for suitable conditions of the magnetospheric plasma and energetic electron populations, could also lead to electron precipitation. Two series of x-ray measurements, coordinated with the operation of the VLF transmitter at Siple Station, Antarctica, have not found evidence of such an effect. However, in no case was there evidence of the transmitted signal or triggered emissions being received at the Siple conjugate point. It is suggested that the negative results to date are related to the absence of suitable conditions for triggering on the Siple field line, but the prospects remain good for successfully triggering electron precipitation by artificial means.
