Conjugate aspects of auroral zone electron precipitation are examined using X-ray data obtained from balloon flights launched from conjugate sites, Reykjavik, Iceland and Syowa, Antarctica, in the winter of 1969. In spite of the close conjugacy of these sites, dissimilarities were noted between observations in the two hemispheres, especially for midnight events. This is attributed in part to balloon drift and motions of narrow precipitation regions. For a dayside event, close conjugate relations were found even though the X-ray detectors were out of conjugacy by approx. 700 km. Riometer data from this event suggest that the intensity of electron precipitation was significantly smaller in the southern hemisphere. |
