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.

62. Tracing p-Mode Waves from the Photosphere to the Corona in Active Regions

Through analyzing a suite of space- and ground-based observations, the authors report that above sunspots, helioseismic waves of different frequencies are able to channel up through the chromosphere and transition region into corona. General pictures of how the waves make into corona are also shown.
