  • KSWC monitors geomagnetic variations around the Korean Peninsula in real-time by using the magnetometers in Icheon, Jeju and Gangneung stations.
  • Geomagnetic observation has been conducted at three stations (Icheon, Jeju, and Gangneung) of KSWC, and the observed geomagnetic data is used for calculating K-indices, which are updated at three-hour intervals.
  • The geomagnetic field has a magnetic dipole consisting of two geomagnetic poles. Solar wind emanated from the Sun and the interplanetary magnetic field alters the form of the geomagnetic field, which causes different observed values of the geomagnetic field, varying by region and time. The increase in solar activity results in a wide variation of the geomagnetic field, which in turn can cause geomagnetic storms. The occurrence of geomagnetic storms damages various electronic systems on the ground and satellites in space, which limits the performance of systems beneficial to human beings such as broadcasting, communications, banking, electricity and electric power, etc.
  • The occurrence of geomagnetic storms can be checked by the observed data of geomagnetic field variation on the ground. In addition, the geomagnetic data including Kp index, Dst index and K index (observation spots) obtained from various observatories can be used to assess space weather conditions. Furthermore, the data are important material with which to build a prediction model in service of space weather conditions.
