Visual Auroras Observed at the Syowa Station-Iceland Conjugate Pair
Conjugate observations of visual auroras were carried out at Syowa Station in Antarctica and at Husafell in Iceland during the northern summer seasons in 1978. Husafell is located about 50km poleward from the conjugate point of Syowa Station. Conjugacies of auroras are investigated based on the data...

| Summary: | Conjugate observations of visual auroras were carried out at Syowa Station in Antarctica and at Husafell in Iceland during the northern summer seasons in 1978. Husafell is located about 50km poleward from the conjugate point of Syowa Station. Conjugacies of auroras are investigated based on the data of the geomagnetically meridian scanning photometers (5577Å) in addition to the all-sky cameras obtained at both stations. It is shown that the auroral behavior during the pre-breakup and breakup phases of a substorm as a whole is similar and simultaneous at the northern and southern conjugate stations, while the conjugacy of the auroras during the recovery phase of a substorm and a positive magnetic disturbance is poor. |
