Abstract:
Following a description of the Evershed effect as observed by John Evershed in 1909 at the Kodaikanal Solar Observatory, we discuss the evolution of our scientific understanding that accompanied the development of the subject of magnetohydrodynamics (MHD). How the modern telescopic observations as well as the computational capabilities are serving to uncover the complex magnetohydrodynamic processes behind this highly dynamical phenomenon is discussed at length.
