During the Voyager 2 encounter with Neptune, a narrowbanded bursty radio component was observed between 500 and 1326 kHz by the Planetary Radio Astronomy (PRA) instrument. Based on the emission occurrence pattern, the radio source has been localized without the explicit use of the Neptunian offset-tilted dipole (OTD) magnetic field model, which is accurate only at distances greater than 4 RN from the planet. We used only assumptions based upon the general nature of radio wave propagation in planetary magnetospheres. A number of different candidate radial positions were sampled. For example, at 1.5 RN, the derived source location was positioned only about 10¿ from the south magnetic pole. The radiation from this source was beamed into a cone of 77.5¿¿6.3¿ half-angle that was tilted about 10¿ from the radial direction to the north-northeast. At other sampled radial poitions, similar source locations were obtained. Due to its proximity to the south magnetic pole, the kilometric emission radio source is believed to be associated with an active auroral region, similar in nature to those found at Earth and Saturn. ¿American Geophysical Union 1990
