Solar P-angle Alignment in GONG Dopplergrams
Anna L. H. Hughes, Irene Gonzalez-Hernandez, Sean G. McManus +2
In helioseismic studies, an observational parameter of primary concern is the P-angle, the angle along which lies the solar axis of rotation for a given image. For the six observin…
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…
Local helioseismology of sunspot regions: comparison of ring-diagram and time-distance results
A. G. Kosovichev, S. Basu, R. Bogart +10
Local helioseismology provides unique information about the subsurface structure and dynamics of sunspots and active regions. However, because of complexity of sunspot regions loca…
