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 conditions .
After revision: Under low electric conductivity , 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 conditions .
