This project supports the study of the interior of the sun by measuring the oscillations of the visible surface, much as one might attempt to understand the interior structure of a bell by measuring how different parts of the surface respond as the bell is rung. By working at the South Pole it is possible to observe the sun continuously for long periods (far exceeding 100 hours) since it does not rise and set during the summer and since the weather is often clear for many days at a time. The long time period measurements are important because many of the oscillatory mode of the sun have relatively low frequencies, and so it is necessary to observe for extended periods in order to measure them accurately. The telescope makes frequent high resolution pictures of the solar surface, and the successive images are compared point by point to determine how the images have changed in brightness between images.

这个项目通过测量可见表面的振荡来支持对太阳内部的研究，就像人们可能试图通过测量钟的不同部分在敲响时的反应来了解钟的内部结构一样。通过在南极工作，可以长时间（远远超过100小时）连续观察太阳，因为它在夏季不会升起和落下，而且天气经常一连好几天都是晴朗的。长时间的测量是重要的，因为许多太阳的振荡模式具有相对较低的频率，因此有必要观察较长的周期，以便准确地测量它们。该望远镜经常拍摄太阳表面的高分辨率图像，并逐点比较连续的图像，以确定图像之间亮度的变化情况。
