Cosmic ray intensity shows significant diurnal variation of day to day basis with wave trains of high amplitude anisotropic events (HDW) and low amplitude anisotropic events (LDW). Using the pressure corrected data of neutron monitor at Kiel (2.36 GV) for Solar cycles 22 & 23, harmonic analysis was performed to obtain harmonics. Trends were
removed by subtracting 24 hours running average from the hourly values. The events of high & low amplitude wave trains were sorted out, total 54 events was selected for solar cycle 22, and 63 events were selected for solar cycle 23. On the basis of geomagnetic disturbance index Ap group (0-5, 6-10, 11-14, 15-18,>19) events were again sorted out of different durations.
It is concluded that low diurnal amplitude wave train event of different durations does not exhibit any effect on geomagnetic disturbances, while high diurnal amplitude wave train event of all durations, equally, are effecting geomagnetic disturbances.
