Auroras Associated with FTE-Type Events Recorded at the South Pole-Frobisher Bay Conjugate Pair

The possible ground signatures of FTE's have been studied by Goertz et al. (1985), Southwood (1987), and Lanzerotti et al. (1986). The impulsive magnetic variations discussed by Lanzerotti et al. (1986) as candidate events for FTE's have signatures expected of moving circular Hall current in the ionosphere, produced by a field-aligned current. In the present analysis we use the magnetometer data obtained from the South Pole-Frobisher Bay conjugate pair at cusp latitudes which are extremely useful for testing the proposed FTE models. We also use the all-sky camera data recorded at South Pole station for studying the relationship between FTE's and auroras.
