106. The vector magnetic field of the Sun-as-a-star during activity cycle 24
105. Waves of Magnetic-field Variations Observed in a Flare-excited Sunquake Event
Waves of magnetic-field variations were observed associated with the sunquake waves that were excited by the X9.3 flare on 2017 September 6. The nature and cause of the magnetic waves are discussed after the phase relations and power distributions of the magnetic waves and Doppler-observed sunquake waves are investigated.
