209. The Magnetic Origin of Chromospheric Moreton Waves

Contributed by Ze Zhong. Posted on March 21, 2025

Moreton waves were studied using a systematic survey of Moreton-wave events observed during the SDO era. The results showed that inclined magnetic configurations act as a wall, forcing eruptions and Moreton waves to propagate toward weaker magnetic fields.

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

Contributed by Junwei Zhao. Posted on October 30, 2016

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.
