Measurements of the location of sources of terrestrial kilometric radiation obtained with the lunar-orbiting Radio Astronomy Explorer 2 satellite have revealed a class of emission associated with the cusp and dayside magnetosheath. At frequencis near 250 kHz this emission is observed at radial distances between 2 and 20 RE at magnetic latitudes of 75¿-80¿ and is most often detected during periods of auroral activity (AE>250) and southward orientation of the interplanetary magnetic field vertical component. During very disturbed times the emission at the lowest frequencies (≲200kHz) appears to come from the dayside magnetosheath at distances of >12 RE. Whenever the geomagnetic dipole is tilted significantly with respect to the ecliptic pole (>10¿), the cusp emission is confined to the hemisphere containing the subsolar point. The measurements also suggest that the region of cusp emission is rather narrowly confined in longitude to within a few hours of the noon meridian.
