| Research Abstract |
Syowa Station in Antarctica and stations in Iceland form an ideal set of observatories to study geomagnetically conjugate auroras in the auroral zone. A campaign of conjugate auroral observations using all-sky TV cameras has been carried out during the equinox periods. We examined several types of auroras, e.g., beads aurora, auroral breakup, spirals, and pulsating aurora, checking for similarity and dissimilarity in terms of shapes, movements, and luminosity variations at both observatories. We assumed their generation region and mechanisms. We were also able to trace the temporal movements and displacement of the auroras in the Northern and Southern Hemispheres with a high spatial-temporal resolution. We discussed their conjugate characteristics with reference to solar wind-magnetosphere and magnetosphere-ionosphere coupling processes.
