Abstract: It is shown that the double loop structure of lunar ionospheric current system fails to develop during winter (December) months along Indian (75°E) longitude sector, analogous to the failure to the single loop current system due to solar quiet (Sq) daily variation of the geomagnetic field during the same season. The meridional currents are shown to have a dominant role in structuring the solar and lunar ionospheric current systems. The absence of solar or lunar current system could be due to the dominance of the dynamo system of the southern hemisphere during certain anomalous conditions.
