内容記述 | Simultaneous auroral observations were carried out at the Syowa-Husafell conjugate pair of stations (L=6.1) in the period of August 28-September 30,1984. During the period of the campaign, conjugate auroral data were obtained on 4 nights of clear sky in the conjugate regions. In this paper, we show some initial results on the geomagnetic conjugacy of visible auroras observed by 5577Å scanning photometers and all-sky cameras in the selected event study of September 26,1984. The characteristics of the conjugacy of visible auroras are as follows, 1) Auroral breakups occur almost simultaneously in the northern and southern hemispheres. However, the poleward expansion speed is much larger at Syowa than at Husafell, 2) The east-west (EW) aligned auroral arcs appear at almost the same geomagnetic latitude in the IGRF model in both hemispheres. However, the EW-aligned auroras observed at Husafell show a large longitudinal displacement (more than 300km westward) relative to those observed at Syowa, 3) Isolated north-south aligned auroras show a good conjugacy in their shapes and locations, 4) The EW-aligned auroras generally show different movements and fine structures in both hemispheres. | |||||||||
