The particle and plasma wave data of the DE 1 and Swedish Viking satellites shows that intense (>1 mV/m) upper hybrid emissions are sometimes present in the mid-altitude polar magnetosphere on both the dayside cusp/cleft and the nightside auroral regions and that waves near the upper hybrid frequency are often associated with electron conical distributions. These observations are consistent with the production of at least some electron conical distributions by oblique heating of the electrons by upper hybrid waves. Examination of the wave data to establish the role of parallel heating remains to be performed. ¿ American Geophysical Union 1992
