Coronal Magnetometry in the Future
Abstract
Coronal magnetic field plays a crucial role in solar activity. However, due to the high temperature, low density and weak magnetic field properties of the corona, it is hard to directly measure coronal magnetic field, especially for the vector magnetic field. In this presentation, I will briefly review the past endeavor to measure the coronal magnetic field and present current methodology. I will introduce in more detail about the proposed Coronal Magnetism Telescopes of China (COMTEC) and the Coronal Solar Magnetism Observatory (COSMO) in the United States of America. Both of them are dedicated to measure the vector magnetic field in the corona as well as chromospheric magnetic field. They, once established, will certainly contribute much to the comprehensive understanding of important questions in solar physics, such as coronal and chromospheric heating, solar wind acceleration, global and long-time variation of coronal magnetic field, etc.
