N2 - Space weather study has increasingly attracts the attention of many scientists to explore the interaction between solar activity and geomagnetic activity. Observation on Pc5 geomagnetic pulsations with periods ranging from 150-600seconds due to solar wind perturbations at the equatorial region currently not widely explored. In this paper, we will briefly discuss the data processing methods involve in order to analyze the geomagnetic data observed by magnetometer from geomagnetic observation stations; Tirunelveli (TIR), India, Langkawi (LKW), Malaysia and Yap Island (YAP), Federated States of Micronesia which are located at equatorial region. The explanation of the processing methods is based on the 24-hour data with 1 second sampling interval extracted during quiet and disturbed days. The result indicates that the higher amplitude of H geomagnetic field is recorded during daytime and maintain during nighttime at all analyzed stations. In addition, Pc5 ULF pulsations are corresponding well with the solar wind perturbations.
