Abstract: The annual and semi-annual components in the first two harmonics of the geomagnetic solar and lunar daily variations (S and L respectively) at Alibag during the period 1932-72 have been calculated. The parameter S shows a dominant annual component with its maximum in summer; the semi-annual component with equinoctial maxima is of much lesser magnitude but is almost equal in both the harmonics of all the three elements, namely, declination and the horizontal as well as vertical intensity. In L, the semi-annual component appears prominent with minima in the equinoctial months.
