On December 5, 1983 the polar orbiting satellites NOAA-7 and DMSP-F6, while in opposite hemispheres, each crossed a narrow structure of auroral electron precipitation at nearly the same Universal Time (UT) and at the same high magnetic latitude local time location. The Operational Line Scanner (OLS) image taken by DMSP-F6 of the northern polar region showed that this enhancement was associated with a sun-aligned arc (SAA) which extended poleward from the midnight sector auroral zone and passed across the polar cap very near to the magnetic pole. The DMSP-F6 plasma measurements showed particle precipitation at background levels in the regions adjacent to the SAA suggesting that those magnetic field lines connected to the interplanetary medium via the northern tail lobe. NOAA-7 observations show that the analogous precipitation structure in the southern hemisphere was embedded in a region of low intensity ion and electron precipitation which had the characteristics of the plasma sheet population. Comparisons between the boundaries of the lower latitude auroral zone precipitation and the electron distributions at those boundaries were also made. The results of these comparisons together with those made for the high latitude SAA argue for a high degree of interhemisphere conjugacy in the electron precipitation over a wide range of invariant magnetic latitudes. ¿ American Geophysical Union 1987
