The Rotation of the White Light Solar Corona at Height 4 R sun from 1996 to 2010: A Tomographical Study of Large Angle and Spectrometric Coronagraph C2 Observations

摘要

This is a major study of the rotation of the corona throughout a solar activity cycle. For the first time, this was made using tomography maps of the coronal structure thus is far superior to previous studies based on autocorrelations of the coronal brightness. This study, for the first time, showed surprisingly rapid changes in rotation rates, and large differences in rotation between latitudes.
