Helioseismology of Pre-Emerging Active Regions III: Statistical Analysis
G. Barnes, A. C. Birch, K. D. Leka +1
The subsurface properties of active regions prior to their appearance at the solar surface may shed light on the process of active region formation. Helioseismic holography has bee…

Helioseismology of Pre-Emerging Active Regions I: Overview, Data, and Target Selection Criteria
K. D. Leka, G. Barnes, A. C. Birch +4
This first paper in a series describes the design of a study testing whether pre-appearance signatures of solar magnetic active regions were detectable using various tools of local…

Helioseismology of Pre-Emerging Active Regions II: Average Emergence Properties
A. C. Birch, D. C. Braun, K. D. Leka +2
We report on average subsurface properties of pre-emerging active regions as compared to areas where no active region emergence was detected. Helioseismic holography is applied to…
