In this paper we have considered the magnetically disturbed days (Ap>20) to investigate the effect of magnetic activity on the generation of ionospheric irregularities. Random velocity of the irregularity which is a measure of random changes in irregularity drift velocity is evaluated. Decrease in the value of random velocity to its lowest value by 23 LT may be due to decrease in the height of F region. Maximum cross-correlation CI(x0,tm) between the two signals recorded by two spaced receivers shows the decreasing pattern which attributes the fresh generation of irregularities.
