| Abstract: |
The purpose of this work is to image the solar far-side active regions using acoustic signals with three skips. The mapping of the far-side active regions was first made possible (Lindsey & Braun 2000) using helioseismic holography technique by use of four-skip acoustic signals. The quality of far-side images was later improved with the combination of four- and five-skip signals using the time-distance technique (Zhao 2007). In this work, we further explore the possibility of making three-skip far-side images of active regions, and improving the image quality by combining the three-skip images with the images obtained from existing techniques.
