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.

60. SDO/HMI Survey of Emerging Active Regions for Helioseismology and Other Solar Physics Applications (SDO/HEAR)

Contributed by Hannah Schunker. Posted on September 28, 2016

We have generated a dataset of emerging active regions (EARs) observed by SDO/HMI that is specifically suitable for helioseismic analysis. Using this dataset we show that, on average the bipoles have a symmetric the east-west velocity relative to differential rotation.
