105. Waves of Magnetic-field Variations Observed in a Flare-excited Sunquake Event

Contributed by Junwei Zhao. Posted on July 13, 2018

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.
