Abstract: Effect of geomagnetic activity on ionospheric drift speed is studied for Udaipur (, 14.55°N).To reduce the effect of solar activity, the study is made with the data obtained during Mar. 1974-Oct. 1975, a low activity period, and only those days for which 10.7 cm solar flux was below 90 have been considered. A negative correlation is found between noontime E-region apparent drift speed and geomagnetic Kp index. An identical relationship is obtained for nighttime apparent drift speed with Kp in case of F-region. The correlation coefficients deduced in the two cases are -0.81 and -0.86, respectively.
