Narrow band emissions at frequencies near twice and three times the ionospheric electron cyclotron frequency have been observed with a ground based receiver located at Two Rivers, Alaska (near Fairbanks). The emissions at twice the local ionospheric electron cyclotron frequency (≈2.50--2.80 MHz) appear similar in frequency, intensity, local time dependence, and temporal structure to auroral ''roar'' events previously observed at Churchill, Manitoba [Kellogg and Monson, 1979; 1984>. The observation of emissions near 3fce (≈3.66--4.24 MHz), sometimes observed simultaneously with the 2fce events, represents a new aspect of this phenomenon. A quantitative theoretical understanding of the phenomenon has not yet been achieved. ¿ American Geophysical Union 1993
