Abstract

Chorus emissions observed on ground based station and in the earth's magnetosphere in January 1999 at Jammu (geomag. Lat. 220 26/ N) are presented. It is shown that these emissions are generated in the equatorial plane (L = 4) by cyclotron resonance between the propagating whistler wave and the gyrating electrons.
