Auroras and Associated Phenomena

  title={Auroras and Associated Phenomena},
  author={Y. Feldstein},
The dynamics of the auroral oval and its dependence on DP intensity are examined. Even during extremely magneto-quiet periods, auroras are observed and located along a contracted oval. In the noon sector, auroras occur at φ ≈ 80°, in the midnight sector at φ ≈ 70°. This is in agreement with observations made from satellites and aircraft.
