Strong electromagnetic disturbances in the auroral region at altitudes of about 900 km, which were recorded by the Interkosmos-Bolgariya-1300 satellite, are analyzed. An attempt is undertaken to determine general regularities in their structures. A specific class of events in which the disturbances of the electric and magnetic fields have the same form are distinguished. The events are a result of the propagation of oblique Alfven waves with lambda /sub z/ about 3.10 /sub s/ km, lambda /sub x/ less than or equal to 10 km, and f about 1 Hz. The lack of an apparent correlation between the mutually perpendicular components of the electric and magnetic fields is due to a significant phase shift between the disturbances of the electric and magnetic fields, which indicates the interference of the waves incident and reflected at the ionosphere.
