Discrete emissions received on the satellite ISIS 2 on august 15, 1978, corresponded closely with the emissions received on nearby ground stations. Over the first part of the pass the signals were more or less simultaneous and identical in shape, but later they appear on the satellite record in a slightly more dispersed form with about a quarter of a second additional delay, strongly suggestive of nonducted travel from the emission region to the sattelite. Ray tracing is used to attempt to reconstruct this event and establish the generation region of the emissions.
