Before revision: Under low electric conductivity conditions, e.g., during night time and during winter, the dynamo region becomes too resistive, leading to ionospheric feedback instability , which is responsible for higher occurrence of aurora under low sunlight.
After revision: Under low electric conductivity conditions, e.g., during night time and during winter, the dynamo region becomes too resistive, leading to ionospheric feedback , which is responsible for higher occurrence of aurora under low sunlight.
