Comparing Solar Activity Minima Using Acoustic Oscillation Frequencies
Abstract
Using the variability of solar acoustic oscillation mode frequencies, we investigate the width and timing of last three solar minima at various depths in the solar interior. We find that the current minimum is as deep as the previous minimum, however, more data are needed to reveal the true depth of the current minimum.
