A new type of discrete whistler mode emission has been observed in the magnetosphere at L30. The analysis of data from the low-altitude ISTS 2 and the high-altitude DE 1 satellites indicates that the emissions may be generated near the equatorial plane at frequencies of ~0.2fHeq inside and ~0.35fHeq outside the plasmapause. The parallel energy of electrons for gyroresonance with the observed waves is found to be ~20--50 keV in both cases. Observations in the vicinity of low-altitude crossings of the plasmapause also indicate the presence of a second emission band which is interpreted to result from the reflection of the equatorially generated emissions from the lower ionosphere. ¿ American Geophysical Union 1988
