Abstract : A new type of whistler, called the hook whistler, is reported. This new type of whistler has been found in the very-low-frequency radio noise data from the Injun 3 satellite. The hook whistler consists of two whistler-like components separated by a frequency dependent time delay varying from zero to about 200 milliseconds. The two components are believed to arise from different propagation paths from the lightning source to the satellite. (Author)
