First Geomagnetic Observation at Sabah, Malaysia by Using MAGDAS Array

Magnetic Data Acquisition System (MAGDAS) Malaysia: Installation and Performance Analysis of Local Data Logger with Kyushu University Data Logger at USM Transkrian, Pulau Pinang

“…The deployment of the MAGDAS station at the ground field is conducted, and the comparison of the data can be monitor in real-time from both Local and Kyushu University data loggers, as shown in Figure 2. The data from both data loggers is compared with the solar event to observe the deployed system's pattern and workability [1], [7].…”

“…3 The direction of magnetic field strength parameters In Malaysia, the magnetic field component of the earth can be check by looking at the WMM. The value of the geomagnetic element can be obtained by the formula of ( 1) and (2) [7]. WMM provides a detailed strength of the magnetic field throughout the whole world.…”

“…The value of magnetic field intensity can be expressed in nanoTesla(nT) [7]. The inclination or dip angle, I can be obtained by the following formula expressed in (4).…”

“…It is important to have many stations along the magnetic equator to investigate the longitudinal variations of the equatorial electrojet [3], [6]. The MAGDAS station installation mostly used MAGDAS II and MAGDAS 9 where the most magnetometer was densely installed at 210 • magnetic meridians, and the other MAGDAS station was located in the magnetic equator region as shown in Figure 1 [7]. MAGDAS I appear in light green color only having seven stations worldwide, and the black triangle symbol is FM-CW radar which is not MAGDAS station.…”

“…Malaysia includes the country that used MAGDAS II and MAGDAS 9. The reason for the MAGDAS station was being installed at the West Coast Universiti Sains Malaysia (USM) was due to the geographic area of the MAGDAS station which is located in the equatorial region and less disturbed from human activities [1], [7].…”
