*Title*: *Helioseismic imaging of the Sun’s far side *
*Speaker*: *Dr. Dan Yang *
 Max Planck Institute for Solar System Research, Germany
*Abstract:*
Helioseismic holography can produce maps of the Sun’s far side using the
Sun’s five-minute oscillations observed from the Earth-facing side. This
technique is known as helioseismic far-side imaging, which enables the
detection of active regions days before they rotate into view from Earth.
In this talk, I will explain how far-side helioseismology works and present
a direct validation using SO/PHI magnetograms of the Sun’s far side. I will
then focus on our work, Combined Surface Flux Transport and Helioseismic
Far-Side Active Region Model (FARM), published in Solar Physics (299, 161).
In this study, collaborators and I introduce a novel method for estimating
magnetic fields of far-side active regions from helioseismic measurements
and incorporate the inferred magnetic fields into a surface flux transport
model.
