Monitoring systems consisting of several magnetometers and cameras were installed to detect artificial magnetic disturbances at the Kakioka, Memambetsu, and Kanoya Magnetic Observatories in Japan. These systems calculate the magnetic dipole moment and source position of artificial magnetic disturbances as a routine matter. For sources of disturbance that are not magnetic dipole moments, each event must be tackled individually. For a non-dipole disturbance at Kanoya from 16 to 22 June 2011, the position and intensity of two lines of direct currents were calculated, and the baseline value affected by these currents was corrected appropriately.
